Just remember the Otto cycle: Intake, compression, power, exhaust.
Or: suck, squeeze, bang, blow!
BUT- being a Toyota that is now DEAD.....he may be stumped.
If memory serves me, the 93 has a timing belt. I believe Toyota has moved entirely back to timing chains over the last 10 years.
Good for them on that change. I hate timing belts.
OP, if it just died and didn't make a strange noise, I doubt it is a timing belt. When a timing belt breaks and the engine jumps timing, you can hear it.
Belt done ~20k miles ago
Last tank of gas, 1 refill post usage.
Would probably be a good idea to change the fuel filter anyways
I suppose you could check the fuel pump pressure before it goes into the filter but for no more effort and a few bucks why not put in a new filter?
My money is on fuel pump.
As someone mentioned earlier. I'd give it a shot of either to see if it fires, first. If it had been running OK and then abruptly stopped, I'd suspect something electrical. One thing you could do is pull fuses and re-seat them along with electrical connectors that are related to the ignition, computer or fuel pump. But be careful doing stuff like that or you could create more problems.
Cam/ crank position sensors could be another area for a sudden stall but that's getting a bit more complicated to check out and I think they'd give you a trouble code. But that year is not very sophisticated in that area so who knows.
One last thing, it could have been running way too rich and that caused it to die on you. You didn't notice any black smoke out the exhaust did you? This was a cold start, I take it.Sounds interesting though, it's fun working on stuff like this. If for nothing but to get a little education.
Thanks. I'll check the fuses, no black smoke, went from running like a top to nothing in a split second.
Take it to a mechanic who knows what the F he/she is doing.
Seems I have a vague memory of small cars having their fuel pump stashed away in the rear panel/trunk area that had a reset button. May or may not apply here.
On a 92 there should be a small box under the hood that you can jump for a flashing check engine code. You should be able to find it on web with flash sequence decodes too. Fuel pump may have a relay, which you can check with a simple multimeter. If you find the relay and tap it, it may start working again temporally.
Forgot, you could re-seat related relays too.
Burno...( keep in mind I'm from the carburetor era ... <groan> ) but... I looked for pre-OBDII thingie info on code reading:
Burno..... <hugs> and, remember the immortal advice of Poohbear: last place first
Yup, They do go bad. My dad lost the fuel pump in his 1990 Accord. PITA to change, drain & drop the tank. He 'thought' he could do it, at 85!
He about got it out, had to get the shop foreman where he had worked (as a mechanic) to come wrap the job up.
Toyota has been timing chain for the Corolla since 98.
Prior was a belt, but as far as I know, no Toyota has ever been an interference engine
Valve timing is more than the belt, you have the tensioner too. Only time I had a valve timing problem the belt didn't break, but jumped enough to be off time and not run, but not enough to bend valves.
If a timing belt job was done, (especially with aftermarket parts, which seem to be declining in quality) it could still be the issue.
Etaops i just assumed it was a belt system. After reading the post above mine, disregard my advice, if it has a chain.
