Hi guys new member, I bought 99 h1 in February very cool ride compare to my old h2, but like 3 weeks ago started to have problems with it. Sometimes it will stalled while runing then it will take a few trys and will start again and continue without a problem, I saw a video in you tube about the lift fuel pump and fuel filter so I replace both I use it for about 4 days without a problem even went kind of far from where I live ( 200 miles) and no problem but today after I got off from work it did it again at the parking lot after a couple starts I was able to get home any ideas? Thanks for any advice.

 

Sounds like a PMD. As they start to fail it can happen intermintently

 

do you have the part number?

 

I have a 97 parts book. I can post the part number for the 97 PMD later. The GM piece is expensive.( 500-600.00 ) There are other providers that are much cheaper ( under $200.00 )
