Question about 1997 GMC Jimmy

1 Answer

Car died after stopping at a light and proceeding up a small hill

I have a 97 GMC Jimmy 6 cylinder 4wd. The fuel pump was replaced with a gm fuel pump approx. 2.5 yrs ago. the car has over a half a tank of gas. The day it broke down it started right up was running fine no rough idling or anything. I went up a pretty steep hill close to my home and then stopped at a red light. Still no problem. I left the light and started up another small hill and the car just died. It tries to turn over but seems to not be getting fuel. The fuel pump is working or at least it sounds like it is. I rented an analyzer for the computer but it came back with no codes. I had the battery checked and it was questionable if it was bad so they replaced it with a new one but that didn't do anything. Any advice would be greatly appreciated. I just need to get my car running. Thanks

Let's start with the simple things. Change the fuel filter first and check the fuel pressure at the shredder valve. The fuel pressure should be 60 to 65psi with the fuel line pressurized and should drop by 5 psi when engine is running. Keep me posted, be glad to help.If there is an Auto Zone around your area you can lone out a fuel pressure gauge and they will have the step y step instructions for you to get the job done. Good luck.

Cylinder 3 misfiring on a 97 gmc jimmy 4wd. Did a tune up about 2 months ago (ignition, wires, coil, spark plugs), replaced fuel pump last week, used fuel injector cleaner, still no luck...any ideas?

go back and check all the plugs, wires and the total tune up. check your firing order, and timing. put a timing lite on the plug wires and if the plug is bad it will show with the light. lol.

2001 Jimmy had fuel pump problems. Replaced fuel pump with after market and fired right up. Week later I stop run into house, then back out completely dead at the key. Replace starter, fires right

I'm a little lost here, but if it will start on starting fluid, the ignition system is working.
Most V-6 GM trucks take at least 65psi of fuel pressure to start. Most aftermarket pumps don't do the job.
I would check the fuel pressure with a gauge next.

Fuel gauge wont work 97 jimmy

Common problem, it can be a ground wire (not any ive seen) the float assy can be bought through your local gm dealer instead of buying the whole pump assy.

Fuel problems 97 jimmy

Yeah, The fuel pump can go bad . The normal warranty on the pump is 12 months or 12,000 miles. This is very rare . I would check if the fuel pump had a lifetime warranty.

I would also check the ignition switch, and all the fuses to make sure the fuel pump is the failure.

Good Luck
