So over the last few days I have done a bunch of work to my T100. I needed to replace the valve cover gaskets. I also changed out the spark plugs with NGK, new wires that are NGK, replace the fuel injectors with remaned injectors. I didn't replace either intake gasket as they were both in very good shape. Well I got it all out back together today and now it won't start. It ran for like 15 seconds the first time I tried to start it but it ran really bad. I would a vacuum line I missed and put it back on but not i get nothing. It cranks just fine but won't fire up. Every now and then it'll act like it is going to, it'll pop then clunk then just go back to turning over. Any help would be greatly appreciated as I am currently over my head.

 

Welcome!

What is the year and engine of your T100?

 

Its a 1996 with the 3.4. I also forgot to mention that i did switch back to the old plugs to see if that would work, it didnt. but when i pulled out the new plugs the driver side was wet with gas and the passenger side was dry

 

Ok so my firing order was messed up got that fixed and now it runs. New question is does anyone know how to get and engine code to flash on the dash. My truck now has a check engine light and no one around me can check obd1 ports.

 

I wish i could help. Im sure someone has a 96 service manual online. Do a search here or yotatech or 4x4wire or ih8mud and youll find it. 96 must be the last obd1 year?
Glad you got it running. I took my truck to a shop for some machine work and they gave it back to me with the wires in the wrong order and told me they didnt know why it was misfiring. I try not to take my truck to shops if i dont have to...

 

On other pre obd2 yotes ive worked on you jump two diagnostic ports with a paperclip...id guess the diagnostic port is under the hood near the main fuse box.
