Question about 1999 GMC Safari

1 Answer

I own a 1999 GMC Safari Van and it stopped running. I can go to start it and it will act like it is going to start but doesn't. I have replaced the fuel pump and fuel filter thinking that it was a fuel problem but it did not fix the problem. I think moved on to using an OBDII and it told me no codes. I then moved on and replaced the distributor and still no fix. Does anyone have an idea for me to try for it will be greatly appreciated. Thank you.

It's the crankshaft position sensor, most likely bad. I just had the same problem, replaced the fuel pump, filter, plugs and wires, as soon as I replaced that fired right up. The part is around $50 and it's located under the vehicle, passenger side.

1999 gmc safari van wipers wont work


check fuse, then run a ground wire to the wiper motor and ensure the ground is good. if the wipers start to work then the motor just needs a permanent ground connected to it. if it doesn`t work then check for power at the motor if you have power then tap the motor with a hammer to see if it starts if so then the motor is bad.

I have a gmc safari van that has the key stuck in the ignition it is running and will not turn offf. How do we stop the vehicle from running?


Probably the easiest and safest way is to go to the fuse box and pull the "ECM" fuse. If the fuse box does not have labels for which fuse is which, just start pulling and replacing fuses until the engine quits.

1999 safari van 4.3 6 cyl. has a service code PO


P0301 is a DTC code that indicates a misfire to cylinder one. It could be a bad spark plug, spark plug wire, rotor and cap, a dirty fuel injector, or the worst a bad head gasket. Cylinder 1 is the first cylinder on the drivers side, towards the front. Start with the simple and check the spark plug wire and add fuel injector cleaner to the gas tank. Good luck and hope this helps you get you van running 100% soon. If that did not help, then your going to have to do a tune up by replacing the spark plugs, wires and rotor and cap. You can get all the parts you need at Auto Zone and they can give you the step by step to get the job done with common tools in under 2 hours of your time. Keep me posted, be glad to know you got your van running 100% again soon.

My dad is having trouble starting his 95 GMC Safari Conversion van after it has been running. After setting overnight the van starts right up. If he runs a short errand, turns it off, then tries to start...


My 1997 safari was doing the same. After being shut off for a short period of time it started as if it was flooded. If I put the accelerator to the floor it would fire up. As well, I had no engine codes to report. I replaced the fuel pressure regulator and everything is great. It was leaking fuel into the engine causing it to act flooded when starting. Once started, the computer system made adjustments for the leaking fuel so the engine ran fine. If you turn the van off and immediately try to start it, it should fire up. (don't give it time to leak extra fuel into the engine)
