1991 Buick Regal engine problems

When it doesn't start have you checked for spark and and the actual fuel pressure?

Its gettin fire but jus want start and wat u mean by fuel pressure

You get a fuel pressure gauge screw it onto the fuel line under the hood turn the key to run and see what it reads pressure wise when it doesn't start. Also you checked for actual blue spark or you say it has fire because you heard it pop while trying to start it when it doesn't start.

Ok and I heard the pop

Test for spark with a old spark plug or a spark tester when it don't start.

I seen a spark wen I did it so I dnt thinks its the spark plug nd I had jus put a new fuel pump on it but the first time it had cut off on me I smell gas

What's the actual fuel pressure when it doesn't start?New pump or not need to check the actual fuel pressure when it doesn't start?If you have seen the things I have seen over the years you wouldn't trust a new pump ether.

I don't have anything to check the fuel pressure and base on things u done seen name some parts on the car u think need to be change base on y its not startin

I am not going to just have you throw parts at it not going to happen.You can rent a fuel pressure gauge for free with deposit at auto zone.Also see if you can rent a noid light to check for injector pulse wen it doesn't start. Have you checked for codes in the computer yet?Make sure the battery cables are clean and tight?

I understand wat u sayin but wat u think it is and ima check the battery cables

I don't know what it is that's why am having you check things to see what were loosing when it shuts off and dies.Without knowing that were just fishing with dynamite.

O ok and it doesn't start at all now

Alright let me know what you find when you check the things I suggested.
