no start issues

[91Supra313]

ok i seem to be having issues with the supra. Before yesterday it was running perfect, and starting perfect. Then I did an oil change and now it won't start. i haven't been able to start it since last night. It did this once before when I was at work. It was not starting then even with jumper cables hooked up since we thought it was something to do with a low battery. We had to do the old school clutch drop to start it. That was like 2 weeks ago. It has been fine ever since then. I hooked jumper cables up this time to see if maybe it was low amps ( even though the battery is brand new as of 3 weeks ago ) and nothing again.

fuel mods are

Walbro 255
550cc injectors
Lex AFM

This is very annoying and I have a show to go to tomorrow afternoon, so I need to get this sorted like, yesterday fast. So please any input is appreciated. Also there are no codes. This is a 7MGTE by the way.

i would check with the starter first, and then the relays

you know troubleshooting is fun!

Do you hear the starter relay's click but nothing from starter. Do you hear the starter at all. I agree it's either relays or the starter itself. Had a similar situation with my old 7M setup, turned out I had to rebuild the starter in the end. Not the easiest or quickest fix in the world unfortunately. Good luck.

found it right after I posted this but i had to go back to work so....it wasn't the starter because the car was trying to start but it was acting like it didnt have the energy. Come to find out it was the CPS connector. Which I found out from the UK supra forum guys, that it is a common problem on the turbo models. I plugged, and unplugged the connector a few times to kind of clean the contacts, and then it fired right up.
