SOURCE: replace starter on 2002 GMC Envoy SLT

check to see if the starter itself is getting a signal to crank. youll need to use a test light and have someone else try to start the vehicle, while you probe the wire to the starter to see if it is getting power. if not, check the starter fuse to make sure its not blown, as well as the starter relay to make sure that is good too (very common on gm's for bad relays) if the fuse and relay are good, but your not getting signal, it is an ignition switch problem.

SOURCE: charge ac

It is located under the hood in the larger of the 2 AC lines, this large line is the low pressure line, also check on the round can the low side line connects to as it can be on that as well, that part is called the Accumulator/reciever drier

SOURCE: 1988 gmc k1500 wont start

hi, check the connections at the ecm,i think it's under pass front seat,i've had a couple of those years loose injector signal at ecm connector,if you have a test light you can unplug injectors and test across terminals ,it's a 12v signal at inj ,if lights flash on both while cranking try plugging in one at a time and see if either sprays, if one does and not the other, you would have a shorted injector

SOURCE: throttle body injectors not fiering but there is fuel pressure

the injectors are fired thru the engine cotrol module but it gets its signal to fire from the pick-up located inside the distributor if you are loosing injector pulse only the ignition module is bad if you are also loosing spark when you loose injector pulse your pick up is causing the problem if you replace the pick-up i recomend you change the ignition module when doing so because they work together and you have to remove the distributor to change the pick-up

How does the crankshaft position sensor operate what is it Job to do? and how do i test the injectors for pulsa with a noid light where are the injectors located on this vehicle?


The crank sensor is needed for the coils to fire. It is on the drivers side, mounted in the engine block back by the transmission. The injectors are under the plenum. The plenum wraps around them. I wouldn't worry about them right now. And your probably right about being flooded. I would throw new plugs in it when you replace the sensor.

The engine will crank but will not start why?


Do you have any codes or an engine light on, in your dash board ? Have you checked for spark at your plugs ? There are many things that could cause a vehicle to not start. Bad camshaft/crankshaft sensors. Poor ground wiring. Defective spark plugs or wires/coils.
