2002 Nissan frontier no start Sign In

Hello thanks for reading I have a 2002 Nissan frontier xe crew cab 3.3l v6 and my main issue is It cranks over and will not start... The truck was In a rollover but minimal damage and still drove for 3 years after just fine.

What I have confirmed is that the car is getting spark, the fuel pressure when the key is turned is above 40 psi, the truck starts if ether is sprayed into the air intake. Also I hooked up a fuel injector testor light and the results were bad it did not blink at all as it is suppose to. So I have assumed that the fuel injectors are not getting a proper signal, From what I have researched It could be the ecm or something related such as a relay or so forth but if I could get an expert opinion on the matter to confirm taking it to a dealer because they would have to test the old ecm while in the truck and program a new ecm while in the truck and this involves towing and stuff. Also I lost my relay/fuse covers and if anyone could point me to the ecm relay that would be appreciated.

The first thing you need to do is see if the injector is receiving power on one of the wires with the key on.

The computer controls the injector with pulsing ground on the other wire.

! Get the fuse/relay covers or maybe in owner's manual just because. I did find pics of them that probably wont show but see if one does..........

^^^^ Was there and not certain correct for this vehicle. ECM if you can't see it is bottom of three to the left in that pic.

Just a question: You said it starts with starting fluid or did you mean it just fires up and dies right out or stays running?
