2002 Chevrolet Express Questions & Answers
02 Chevy Express Van, no acceration when i throttle the gas pedal
I need to know your vin?
I looked at online partsbook for your year--make--model and engine size, I looked up fuel injector, It showed the spider fuel system. That fuel system is noted for problems. At key on engine off, fuel pressure for that system is 60--66 psi. Once it is running it will run with less pressure. You may need to check fuel pressure, key on engine off--idling and under load. That fuel pressure sounds low to me?
I need more info about your fuel system?
Problem with turn signal when headlight is on
this sounds like a earthing problem , so check the wiring for the head lights, see if any wires are trapped between something, bare wire touching car body , anythingthat doesn't look correct, could also be the indicator lever itself with a problem , but check the headlight wiring first
I have a 2002 Chevrolet express with 5.7 engine that loses power up hill and engine starts clattering.
You need to find another mechanic that knows ignition problems, I have never not fixed a misfiring engine that I was assigned to fix, that is a 35 year career. If you read the fault codes you will know which engine cylinder(s) is misfiring, from there it is easy. Any Autozone or other parts store will read the fault codes for free, just ask for a OBD2 fault code test.
I would replace the spark plug wires, when you do it make sure the cables are routed as from the factory and that all the plug wires are placed in the plastic loom holders, failure to do this will cause a misfire in a very short time. You can buy all the parts including the looms here for a much better price than local stores.

Pick-up coil
2002 express doesn't have a pickup coil - it has a camshaft sensor in the distributor, the crankshaft sensor is located in the lower corner of the front cover. Crank sensor is straight forward to replace, the Cam sensor you remove the dist cap and rotor - spin motor over until notch in the shaft lines up with cam sensor, remove bolts and slide up.
