98gmcyukon4x4 -last couple of days (6-7) the truck likes to play games with me sometimes she will start right up no issues an other times it will start but then die within a second or two after i release the key from the start postion. but when i try it again it starts fine ive had at least 2 tanks of gas ruling out the bad gas excuse , it does sound fuel related maybe timing but im leading more to a fuel issue ive been thinking its my inline fuel filter under the passenger door tucked in the frame . but not sure any suggestions

Yea could be on an s10 I have the filter was blocked and it basically did hat then just didn't start unless I put gas in the carb directly. Try the filter

i think im going too ive never changed it 187k so im pretty sure thats the problem cheap fix , i know there are tech two on this truck counting the one in the tank but is there one on the engine right b4 the fuel rail?

 

[Gzes]

Yes I believe so on the s10 there is but I couldn't find it so I just sen it in and it was cheap and quick

The one on the fuel pump is a sock. The other is on the inside left frame rail under the front door. When you let go of the key are are letting it snap back hands off or releasing it softly? if power to the pump is getting killed you relay may be goofy as well. On 1998-on the pcm has full control over relay so no issues with oil pressure switch controlled pump any more so you can eliminate an oil switch as a cause.

releasing it slowly also its sucking more gas than usual

Get yourself a fuel pressure Gauge and I will give you some test to run.

where can i get one autozone ? how much

 

[SunlitComet]

autozone will lend you one with a $150 + tax deposit put down in case you decide to keep it. Otherwise refunded when returned.
