All,
I need help with some common no start things to check on my car. I just moved and am still unpacking my stuff (manuals wiring diagrams and tools), don't have internet access at home yet, and have not had much chance to troubleshoot the car yet.
87 TR
factory ecu, TT chip (does not have no start feature), all stock style setup maf etc.
Car started fine drove onto trailer, towed it to my new place, started fine drove off the trailer and parked it next to my garage. I put enough things away in the garage the next day to make room for the car and now it will not start.
The battery is good, starter is good engine cranks over, and can tell it has compression from the sound. When I turn the key on the fuel pump does not run, so I thought maybe pump or relay was bad so I hot wired the pump. With the pump hot wired it runs and I can hear the fuel flowing through the fuel rails. Then when I tried to start still nothing. So either the injectors are not firing or no spark or both. I checked the fuse labeled ECM (with a meter)it is good. The ground to the fuel pump is good I only had to hot wire the positive side.
When I get my timing light unpacked I will attach it to a plug wire and see if I have spark or not. I have not had time to use my meter to start checking for power everywhere.
So with that back story I need some common causes to look for that would prevent the fuel pump from running and either no spark or no injectors firing. My gut feeling is either positive power supplied to the ECU or a ground that is common to fuel pump relay and computer, ignition etc.
Thanks in advance for any help.
