ok hopefully someone can help me. about 3 weeks ago my truck was having fuel issues (ie starting then stalling, hard starting, eratic throttle, hard acceleration and such) so i replaced my lift pump about 2 weeks ago. that solved the problem for about a week and then they came back. today i replaced my oil pressure senor and no i cant even get the truck to start itll turn over but it wont fire. https://www.dieselbombers.com/images/smilies/stars.gif

Do you have fuel at the injectors ??

 

i havent checked. i had the truck running after i threw the LP in no problem and now after i installed the ops it doesnt want to fire

 

Did you put a AC/DELCO OPS in the truck???cheap off brands suck spend the extra $ on genuine parts ans save time and $$$$$$$$$

 

Ok but it's a brand new sensor should it at least work?

 

About 3 months ago i replaced my CPS with a BWD brand it was crap tried 3 more before getting an AC CPS and now it starts and runs like a new truck and besides parts manufacturers make millions of parts each year and no one is perfect

 

Ok fair enough but I even put the old sensor back in and it still wasn't firing up

 

Ok try running a jumper wire from the positive terminal on one of your batteries to the G terminal on the ALDL port under the dash and crack open the T valve and see if fuel comes out if not you may have a bad LP

 

Thanks for the help so far I appreciate it!, but I believe I found the problem. I opened the tee valve and I had fuel all over the ground so there is a hole between the lp and the tee valve. Also the lp is 2 weeks old

 

Yep that will do it
