I'm brand new here and I need some help on my 1991 S15 Jimmy. Can anybody help me?

I have replaced the gas tank and fuel pump and I am getting gas all the way to the TBI but still getting NO gas into the TBI. I can start the truck by spraying gas directly into the TBI. What can the problem be?

Have you tested the pressure to make sure that it is appropriate (8-10psi)? Have you checked that the injectors are getting their pulse to open from the ECU?

 

Purchasing a Fuel injection pressure tester and a set of NOID lights will set you back about 70 dollars but are a valuable tool and you can make your money back from friends in no time diagnosing their problems.

I bought my NOID light set on a sale day for 10 dollars at Princess Auto and there is about 10 peices for various auto manufacturers and comes with a nice locking case to keep it all clean and dry. And my FIPT was about 50 from the auto parts store near me, I bought a lock and lock container from the dollar store to keep it all in. The noid light goes onto the connector you take off the injector and flashes if the CPU is sending the pulse. If it doesnt light up then there is no pulse. The FPIT unit screws onto your test port and gives a live reading of the pressure on the guage.

Ive used both of mine quite a few times since purchasing them.

Kyle - Any idea what NOID stands for????

 

NO IDea why, but it works. LOL
