Volvo wont start - no power to the fuel injection after power reset.
10

Asked by Pedro Aug 28, 2018 at 11:04 PM about the 2004 Volvo S60 2.5T

Question type: Maintenance & Repair

I recently had my Volvo fail smog.

The fixes seemed simple. One was replacing the PNP sensor, and the other
was cleaning the computer ports.

I followed instructions on youtube (first mistake).
I pulled out the computers , (After disconnecting my battery), and used a tiny
bit of the cleaner they suggested.

I replace the computers modules.

I went to start my car, and it would not start.

I had someone help me check all the fuses and power, and as it turns out, I am
not getting a power pulse to the fuel injection as I turn the ignition.

All fuses are OK. I tried switching out the Engine control relay. I made sure the
computers are in all the way. The battery is good, alternator is good.
I am not getting any new errors from my scanner. All other electric functions
are OK in the car, and everything was working well before I made this huge
mistake.

Does anyone know what could have happened?

Solved issue: Turns out the computer was not properly placed back in with the plastic tabs fully pressed in. Once I tried to set the computer again, and it fully set it, the car started right away.

I had to properly reseat the computers back in, bought the $20 or so tool that looks like a big salad fork. Car started right up. Purple plastic slides have to go all way in.
