Hello,
I have a '95 Celica ST auto with the 1.8 liter, 177k miles. Car is completely stock, well maintained, and has run with no issues until now. It drove normally until a couple weeks ago while driving it all of a sudden, at low speed, sputtered a little then died and would not restart. It turns over normally (not fast), just won't start. The gas light had just come on, so I tried putting another gallon of fuel in to no avail. I towed it home and have been troubleshooting since but I'm stumped. What I've done: Checked for spark: spark is there, but not "bright blue" like the Chilton says it should be. Was more orange/blue. - replaced plugs (gapped to 0.31) - tested wire resistance - less than 10k ohms so OK. Distributor cap posts had a thin white crust on them, and rotor looked 'burned', with a thin black layer of crust and well worn - replaced cap and rotor - signal generator resistance G+ to G- = 214ohms, NE+ to NE- = 424ohms (both in spec) - ignition coil Primary Resistance (+ to -) = 1.7 ohms, Secondary Resistance (+ to terminal) = 11.4ohms (both in spec) I looked to check the Crank Position Sensor resistance but this engine/year does not appear to have one. - Fuel pump primes when jumping the +B and FP terminals, as well as when attempting to turn over. - fuel inlet pipe feels like it's getting pressurized when jumping fuel pump - Timing belt was changed 30k miles / 3 1/2 years ago. At this point, the only thing left I can think of is: 1) test fuel pressure -- I'd have to borrow a gauge 2) compression test -- also need a gauge, although I highly doubt something internal broke as the car has run perfectly up until now Is there something I'm missing? Should I just try replacing the ignition coil and/or distributor?

Forgot to mention:
- Engine light is not on, no codes stored. - I swapped EFI relay with one of the fan ones thinking it might be that but no luck - tried multiple times spraying starter fluid into the intake after the air filter with no change. Throttle normal and 100%. This is what led me back to ignition -------------------- '03 911 Turbo [pics] '95 Toyota Celica [pics] ex's: '01 BMW M5, '08 G37S Coupe 6MT, '98 Trans Am WS6 M6, '98 Trans Am M6 conv't, '97 Mustang Cobra conv't, '92 Stealth Twin Turbo |
