Just bought a 88 supra turbo have a couple questions

[rolohaun]

Hey Everyone,

I just bought a 88 supra turbo and I have been trying to get it running. It turns over just fine but won't fire. I just had some questions from what I have read about other people having starting issues. Things I am going to check :

- Trouble codes ( Can this be done if the motor will not run? With the key on th on position with it give me codes? )
- Fuel ( Whats the best why to check if I'm getting fuel? )
- Fuel Pump ( Not clear on which terminals I have to jump to test this )
- Spark

Car ran in april supposedly and everything looks in order, this is my first supra and I am still new to them. I have searched but found little help about checking if I am getting fuel and such.

Thanks

Hi and welcome!

Here is the link to the TSRM. The lifeline of all MKIII owners!

Codes: Yes, the car will give you codes with the key on the 'ON' position and the jumper installed properly. Refer to the above link for jumper location and instructions.

Fuel: You can check to make sure the fuel pump is working by installing a jumper with the key in the "ON" position. Again refer to link above.

If the car sputters and sounds like it's trying to start, pop the hood and shake/rattle/move the CPS and associated wires. You may simply have a bad CPS wire!

Good luck and post findings!

spaying starting fluid directly into the throttle body while cranking is a good way to see if its NOT getting fuel.

Check your engine error codes and get back to us. The engine doesn't have to be running to do this...just turn the key to the "on" position.

was the motor disassembled any? check timing and cps wires

Also a possibility is bad igniton lock connectors...which seems to be MY issue.

UPDATE

I checked the codes and there are none, checked the fuel pump and the jumper wire sparked and got warm so power there. I sprayed some starting fluid in the throttle body and the car started for half a second so it's no getting fuel. When I got the car the tank was empty so I put 16 liters in it about 3 gal is this enough? should I put a little more in to prime the system??

Thanks!

3 gallons should be plenty. take it you havent checked timing yet. mine was one tooth off and would run like poo, would give it gas and it would die

I will check the timming but I don't think thats it, it seems to want to start. I will put new spark plugs in it too as I have no clue how old they are. Maybe a new fuel filter.

turn the ignition to on, and jumper +B and Fp. If you hear the fuel pump and can hear fuel passing through the return line, the pump isn't your problem.
