Topic: 1981 Toyota Cessida 6 Cyl

Not a 4WD i know but I wasn't sure where to post this one...

I got an '81 Toyota Cressida Wagon what has stopped working and I am at my wits end. It cranks fine, there is spark at the each cyl, there is fuel pressure (FYI this is a EFI), I have no signal to the injectors... So no fuel is getting shot into the cylinders. What other than the ECU controls the fuel injectors? Any hints on anything else I can look at someone told me it was the pick up in the distributor that was but I'm not to sure I was also told the ignitor that sits on top of the distributor coil was but I'm not convinced on that one.

i would say find an ecu somewhere to put in to test it.. my buddy has had this happen with his 22re and that was the problem if you ahve tried that and thats why you asked other than ecu I couldnt tell ya

81 and EFI? Is that the 5MGE engine? 81 and EFI?? I'm surprised about that..

yes thats the 5mge  and yes it is EFI

my money is on the rust in the gas tank.   I found this to be the problem on the "Vmans kanuck runner"  http://board.marlincrawler.com/index.php?topic=49846.0

I beleive that was the only other car out there that had the 1st gen Supra engine.

did you try to prime it to get it to fire?  get a schematic and look for the ground to the cpu.  Should be constant power switching ground system,  Look for what has the same gound or fuse and see if that is working.  is your spark good enough to jump from the boot to block?  I have found even able to jump a plug not good enough to ignite.  Using known good parts is a good start before buying a new cpu if you can't figure something out.

It will turn on when i squirt fuel into the upper manifold.

Neat; I was under the impression the 5M series came out in 82 with the MkII Supras. Learn something new every day!

so that means your not getting fuel, check your pressure before the fuel rail, I'm not sure where there is a port on that one, open your fuel tank door and take the cap off.  have someone stand next to it and turn the key on, you should hear the pump prime if not bad pump or no power to pump.  Get a dmm and check for bat voltage at pump, if so change pump or find open.

check the fuel filter yet?
