Fuel Pump Replacement Steps

markhorner — Fri, 08 Mar 2019 23:43:00 GMT

These are excerpts from mail posted in 1999 that will help understanding the pictures. I have posted these now (2/10/01) as a result of inquiries I have had into fuel pump replacement information. Some months back I had a code 55 and traced it down to the secondary fuel pump. I replaced it with an Airtex E3904 which required that the electrical connector be modified to fit. The instructions called for cutting off the old connector and putting on a wide spade design. I decided not to “cut” anything but instead fashion a male to female extension that would adapt the two. (UPDATE: I changed to the PERFORMANCE ELECTRIC Part # P240KC over the Airtex) Symptoms: Low pressure on the fuel rail. (<43psi) and/or engine shutting down after about 30secs of operation. It will restart then shut down each time. Procedure: Disconnect battery. Remove tank cover lid. Plug filler tube with rag. Remove hoses to pump assembly. Find connectors tucked up under and disconnect. Remove the 8 bolts holding the assembly to the tank. Carefully pry the assembly loose then lift up and rotate. The key to getting the assembly out is to alternate between CCW and CW as you come up with the unit. This is also accompanied by tilting forward and backward at times. The next few pics show the CCW and CW and upward movements. Careful when you get the unit up this high. There is an arm that sticks out that has the float on it. Note the green tie-wrap that holds the connector on. I added this since the connector was almost off. Close up of connector. Expected Result: The fuel pressure will be > 45psi

Coolant Recommendations

host1 — Wed, 13 Nov 2013 23:57:00 GMT

By Marc Haibeck Since it is possible that organic corrosion inhibiter softens the head gasket material, coolant containing organic corrosion protection should not be used in the LT5 engine. The possible values of using organic corrosion protection are small. Dex-Cool claims extended service interval and possible longer water pump seal life. It is not worth taking even a small risk for those benefits since the consequences of head gasket damage are huge. Use coolant that has the following characteristics: - Labeled, “For older vehicles.” - Coolant that is colored green - Texaco UPC number 76568 12016 - Chevron UPC number 23968 10000 - GM specification 1825M coolant. The current pn is 12378560. - AutoZone part number 540722. The UPC number is 52948 59081. - Blue Mountain UPC number 74804 01858 The green coolant might not be available in a brand that you like. However the correct formulation is more important than the brand. Avoid “Universal” coolant. There is no need to compromise when the green coolant is available. Retailers like universal products because they reduce inventory costs, universal coolant is not the best for your LT5, the conventional green coolant is. For detailed information about my observations of LT5 head gasket swelling see: http://www.zr1specialist.com/HAT%20W...d%20gasket.htm

Symptoms: Under normal use you'll see MELTED plastic in the bulb holder on the two underhood lamps. See image on the right. Also, a dead battery from leaving the hood open is a common complaint. What you will be doing is replacing the standard bulb with an "LED bulb assembly". The stock bulb holder is not modified so that a standard bulb can still be used later on if so desired. Click on any image to see close-up. When you do so, use your browser "back" button to return. Tools Required: Phillis screwdriver, small wire cutter, soldering iron, solder, needle nose pliers and an exacto cutting blase (or sharp pocket knife. Also: 1. One 5.8 ohm 1/2 watt resistor 2. Two 3/8 in wire lugs 3. 24 LED board 4. short wire segments Procedure: The picture on the right shows the stock yellow engine lamp on the left side and the white LED replacement on the right. First you need to kill the power to the engine lamps. Either unplug the connector that goes down the hood over to the right of the passenger side head light or disconnect the battery (or if you have a switch installed) Remove each GLASS cover on the Engine Lamps by removing the top screw first then loosen but leave in the lower screw. Now take out the glass from the top leaning it forward then lift up. It is important to control the extraction of the fragile glass cover. DON'T DROP IT! Note the glass piece is "keyed" to fit only one way. If you get it upside down when you reinstall, it won't fit. Find the two wire lugs and remove the plastic around the base. Flatten the base out then cut and bend as illustrated. Board Assembly Steps. 1. Solder the two formed lugs to the board at the indicated locations (click picture to get BIG view) Note, use a sharp blade to remove the green solder mask from the copper at the two locations. 2. Solder two wire straps (lower left and upper right) 3. Solder the 5.8 ohm resister in place. You now have an LED bulb assembly.Note assembly show has not been dunked in the hermetical sealing agent.) The unit shown is sealed against the weather. This is the back side of the board. This is the business side of the 24 LED board. Dome LEDs are utilized due to their superior directionality (who wants light shining out to the sides of the car like the stock incandescent bulb or flat surface mounted LEDs?) This is a close-up of the mercury switch inside the stock bulb holder.It pops out but there is no need to remove it. It is important that no part of the board touch this silver bullet looking switch. I recommend putting two layers of black tape over it if it looks close to touching it. The way this works is the mercury switch closes and turns the lamps on when the hood is in the up position. See the "Section 8A" manual on page 114-3 for more details. You're ready to install the LED board. Do so by inserting the lugs in to the clips. The lug closest to the resistor goes into the bottom bulb clip.This is important because LEDs are polarized. They only work plugged in the right way. Push straight in on the lugs so they don't bend. If necessary use a flat blade screw driver to open the clip a bit as you insert the assembly. Finished product , two very bright white lights. I have tested these repeatedly by leaving them on all night long. The battery does not die. The current draw is 50ma per assembly which is about the same as the car drains while sitting with everything off. Amazing efficiency on these LEDs.They generate light not heat. Actual image taken with nothing but the new LED underhood engine lamps This is the schematic. The diodes are set in a series/parallel arrangement for efficiency. Less power is lost because a smaller dropping resistor can be use.The resistor is mounted in the middle for a proprietary reason. A significant advantage is had by using "through hole" mounted devices here over surface mount. Mechanical advantage is one. The other is for upgrading at a later time. The image to the right is segmented. If you click on the chart you are taken to the "Circuitlab" website. if you click on the schematic you'll get an enlarged schematic. Expected Result: The 24 LED boards will draw 0.05A each. The standard bulbs draw 1.0A each. The LEDs are up to 3X brighter than the standard bulbs. That is 5% of the power of the stock bulbs but still 300% more light.

Replacing the battery

host1 — Thu, 26 Apr 2012 18:20:00 GMT

Procedure: Turn ignition switch on (without starting engine) and turn wheels fully to the left (as though you are making a left turn). This will provide plenty of clearance to the torx fasteners at the rear of the left front wheel well. Once wheels are turned, shut ignition off and remove key. Using a T30 torx head wrench, remove the top three fasteners at the rear of the left front wheel well liner. These are located just in front of the left front fender at the outer side of the wheel well liner. Using a 10mm socket, remove the bolt at the rear and top of the fender. You can now carefully "tilt" the fender panel outward. To provide additional clearance for the fender, use an open faced 10mm wrench and loosen the bolt at the bottom of the fender. There is a narrow slot through which you can insert the wrench. I small flashlight is helpful in seeing this bolt. Since the bolt is upside down, make sure you turn it in the correct direction to loosen and later re-tighten it. Once you have loosened this bolt a few rotations (without removing it), you can now tilt the fender outward enough to have plenty of clearance to lift out the old battery. Using a 13mm socket, remove the battery hold down clamp located at the bottom middle at the rearward-facing side of the battery. There is pretty tight clearance on this, and I had the best results using an 8 inch 1/4" socket extension bar, approaching the hold down bolt from the top. Disconnect the cables from the battery using the correct size metric socket 8mm. Remove the negative cable first, which is the outward cable, followed by the positive terminal cable. Once the cables are disconnected, carefully lift the outward side of the battery slightly upward to lift it above the retaining nubs in the battery tray (in other words, you can't just slide it straight out). Once you have cleared the battery tray, you can now lift out the old battery. Remove the battery insulation sleeve from the old battery and transfer it to the new battery (AC Delco 75-7YR). Lift new battery onto the battery tray and slide it inward into place. There are some wires running down the back which are very tight clearance to the battery, so make sure you hold these rearward while sliding the battery in so that don't catch the battery insulation. Reinstall the hold-down clamp. Connect the negative battery cable. Connect the positive battery cable. Lift the fender panel back into position and just start to thread the top 10mm bolt. Reinstall the three T30 torx fasteners in the wheels well splash panel. Make sure the fender panel is aligned correctly so there will be no interference with the driver's side door's range of motion. Tighten the top 10mm bolt with the fender panel in correct alignment. Tighten the bottom 10mm bolt. Start car and be happy again ;-) A couple of notes. On my car, the battery was definitely dead. The engine fired right up with the new battery. Also, the correct AC Delco replacement battery (75-7YR) has the condition "window" located on the wrong side (near the positive terminal), so it is not visible once the battery is installed.
