AC 41803 Drivetrain:Four Wheel Drive;
@Gap .045" This is a Platinum High Performance Spark PLug


Option : ASP AR25
EngineVIN:W;
@Gap .045"@ High Performance

Stay away from those Gimmick Spark Plugs , they are just more money for nothing. A good platinum spark plug is all you need, the key is to gap it correctly to your application...

On GM products Vin # W it is .045 plug gap
On Gm products Vin # Z it is .035 plug gap

You will not have huge gains in fuel mileage from replacing spark plugs except to say that if your old ones are just extremely bad, there is no magical spark plug with extra mileage manufactured into it.... Hope this helps...

Testimonial: "Thanks for the reply. Spark plugs are pretty basic, but I would have fallen for the higher end. Assume I have VIN W as there is no Z in the vin number"

My jimmy wont start have 58 psi of fuel pressure good spark but the spider injection wont open to spary the fuel brand new 280 bucks for it have checked grounds two broken one fixed those still no start...


check your ecm-ign fuse.if it is ok check to see if you have power to your spider injector.if you have power, you either have a bad computer or a bad connection between the computer and the inj.do you have spark??.if you have no spark check your ign module or bad connection at the ign module.i have seen that before.

Car won't fire


if you have checked for spark at the spark plug end of the wire and it was not an sporadic,then you need to check the fuel pressure at the fuel rail reed valve,it should be at least 50psi ti start an engine thru the injectors

Rough idle(rich) stalls in gear


Basically clean up before use like opening the plugs and adjusting the spark gaps, spray some carb cleaner at the intake & if The soud of the engine smoothens even slightly, then add some it to the fuel in the fuel filter & gun the engine a few time. Flush the radiator and fill in frsh coolant/water. Check the level of water in the battery and top up with distilled water. Clean the air filter and check fan belt tightness. After these small maintenace checks it should run OK.......sodeep

Fuel prblem


the computer controls the fuel injectors.they should measue about 1.4 ohms each.
put fuel directly into the throttle body and see if it will start.
check the wiring to the safety netral switch and all the grounds.
make sure that the ecu is seeing an input from the ignition switch.otherwise it will not turn on the pump.it is a complex setup and you need a wiring diagram
