Pontiac Repair Questions? Ask a Mechanic for Answers ASAP
Hello and good morning. Just to make sure, I show your car having a 2.2 liter instead of a 2.5. Here is from the fuse box to the fuel pump and lead to the fuse box from the ignition. Link the two by the fuel injector fuse.
Your JA Expert,
Have power to pin G7 from fuse #48, but no power at J7 from #46 relay. Can you help me?
This is in the underhood fuse box, is that where your A/C fuse is located? Also, what is the production date of your car, maybe there is a discrepancy in model year.
Yes, I will certainly help. The fuel pump relay is not being activated by the computer, that is why you have no power at J7. My diagram also shows the fuel pump as relay 18. Here is a picture of the relay/fuse box under the hood that these items are located in. Let's make sure we are on the same component and talking about the same locations.
No everything I sent you was for a 2.2 liter 4 cylinder. There is a plate in the middle of the valve cover. Remove the plate and you will find the coils. Remove one coil and perform this test with the coil. It has an ignition boot that fits onto the spark plug built into it.
Please specify---there is spark at the plug but explain how to hook up the LED light. Is it plugged into the fuel injector wires or do I plug it into the spark plug wire?
If we have a no start due to no fuel pump actuation, we need to stick with relay #18
Ok, then your next mission is to check fuel pressure. It sounds like electrically you have power to the fuel pump.
There is electric now to the fuel pump, but pump doesn't run. Thank you for being so patient and working with us and your input is really appreciated. We will be using this web site if/when we have more vehicle problems. Thanks again.
You are very welcome. Actually before you condemn the pump, I want you to check terminal J6 for power. That should show power at the same times as the other test. If that shows power, then the fuel pump is to blame. If it does not show power make sure fuse #48 is not blown. If it's not the relay is to blame.
