1994 GMC Van Repair Question
I have a 1994 GMC Vandura van. Is there a crank sensor or cam sensor on this?
So far we have replaced distributor cap, rotor, plug wires, fuel filter, fuel pump. We have 60 pounds of fuel pressure.
We don't know what else to do to get the van running. PLEASE HELP ASAP. Thanks.

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, Do you hear the fuel pump come On when you turn key on? If not check fuel pump fuse and fuel pump relay if okay-check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,coil's resistances,cap and rotor,distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it and keep testing
Thank you for this information.
