1997 gmc jimmy wont start all the time

Replaced the fuel filter a couple weeks ago and it ran but it had a miss at low speeds but when yu give it gas it took right off. and now it wont start some days. seems like when it starts it it ok for the day or several days after just once in awhile it wont start at all. i even poured a little gas right in the throttle body and it wont hit at all.

I had the same exact problem. After spending thousands on parts. It finally proved to be the CPI injector assembly. Change that and you're truck will be like a whole new vehicle. Most parts store sell a conversion assembly to MPI injection it's a much better desighn that the CPI. I was going nuts for a year chasing this problem. I hope this helps.

My gmc jimmy truck starts with starting fluid then stopS


sounds like no gas getting to the carb. plugged fuel filter, fuel line, bad fuel pump. the carb should squirt a little gas when the throttle is pumped. leave ignition off while looking down the carb and pump the throttle linkage to visually check that gas is squirting down the carb with each stroke of the linkage. maybe you are just out of gas!!

98 gmc jimmy decided not to start after sitting in the cold for a couple days.its trying but not getting gas.I seemed to have run low on fuel so I topped it up but killed the battery tryn to start it. then...


Most likely its the fuel pump on this vehicle they last 10 to 12 years at best and when you ran it that low on gas that finished it off the gas cools the moveing parts in the pump motor. But don't feel bad it would have went anyway and you could have to had it towed. Chevy had some problem with this pump and the whole fuel system disign wholes in there tanks fuel line rusting out wireing problems to the pump. But there a lot of upgrades to the new ones that fix these problems. You could try replaceing the fuel filter its under the drivers door mounted to the frame rail but i know these vehicles and fix this problem to many times. And you should know its not cheap depending on what needs to be replaced the fuel pump is inside the fuel tank and that needs to come out. Well sorry for the gloom and doom but its the reality of owening this vehicle all i can do is wish you luck
