I'm having an no start issue on my 95 PSD. It began having issues about a month or two after installing my TS Performance chip. I followed all instructions cleaning the contacts on the PCM and securing it with tape to be sure it wouldn't slide in and out. Also my keys were out of the ignition and batteries disconnected.
It was two weeks ago when it began fast cranking with no start, however, after trying a few times the truck would start and run just fine. But just last weekend it died on me while I was driving so I knew then it was time to look into it. Thinking my chip was the problem I removed it and put it back to stock. This did not solve my issues as my truck would start occasionally but die shortly after. Driving to the store and back it died on me about 8 times starting right back up each time. While running the truck sounded healthy no signs of a misfire etc.
Now the truck refuses to start no matter what. It has brand new batteries so I can rule those out. I've done quite a bit of research trying to get to the bottom of this and performed a number of tests and replaced a few different parts including : replacing the CPS sensor, fuel "lift" pump, replaced the blue hoses, cleaned contacts on all sensors including ICP even tried unplugging that one and cleaned valve cover harness plugs, checked all fuses including the 30A #22 fuse, swapped IDMs with a buddy's 7.3 SD that runs good, even put the horn relay into the IDM relays position to see if that was my issue.
When key is in the ON position with engine OFF the wait to start light illuminates as it should and while cranking the oil pressure gauge builds pressure and my Tach is showing approximately 400RPMs. I have not been able to put it on a scan tool because I do not have access to an advanced on like AE or snap on to run buzz tests etc.. Plus I'm do not have any check engine lights so I am not even sure its throwing any codes. My head is spinning trying to figure out what is wrong with this truck
I appreciate any feedback I get as I rely on this truck as a daily driver.
Thank you all in advance ,
