ok heres the deal, this is a 94 gt (2.2l) i had to change out the oil pump gasket since it was leaking about 2 quarts a day, while i was in it i changed the tiiming belt also. I had the marks lined up, and while i had the covers off and motor mount etc off i cranked it up to make sure i had it set right. Well it started up fine. So, i put everything back together and now it wont start. It spins over but makes no attempt to fire up at all. So far ive checked fuel pressure (good) , spark is correct ( i pulled a wire to make sure it was working) , and double checked timing by putting the crank mark on 0 and checking the rotor button. So i have spark fuel and air, but still no startup. Currently im into the computer wiring hoping i may have stretched or pulled a wire loose somewhere, and that is taking forever. Has anyone had this problem before? the computer isnt throwing any codes (i cant really crank it anyway so it stays in open loop), so i dont really know what to do except go one wire at a time and try to find a missing link. If u guys have any suggestions it would be appreciated, thanks

What the heck is an oil pump gasket?

Here's what my dad has concluded about your problem, 2 questions.
After changing the oil pump gasket, did you change the battery gasket and your blinker fluid gasket?

what about the crank position sensor? get it plugged back in good? Any codes to read out?

haha good one

well from what ive read the crank sensor is on the other side (dist side) of the camshaft, i'll have a look but i dont see any wires besides the big harness that were even touched in the process.

and spunky393 thats funny.....but seriously there is an oil pump cover gasket that goes around the top left of the oil pump housing(it houses the actual oil pump gear, and the gear itself comes off with that section of the housing. I didn't know anything about it when i went in, i assumed it was a front crank seal but started it up after i had the covers removed to try to find the source of the leak. it was a PITA finding that gasket b/c no parts stores around knew wtf i was talking about, even bringing it in to show them (i.e. Oreilly's employee says: so what kinda transmission this come out of anyway), but i lucked out at a local import parts store that knew what i was talking about and even had one in stock (amazed, as they usually have NOTHING i need)
oil pump
the gasket i had to get is located in the top left of the housing, has like 6 bolts around it and it also holds the gear in place.


anyhow back to the problem, ive traced the wires for the injectors and they seem to be working properly, engine isnt throwing any codes (probably doesnt help that it wont start now), ive triple checked the timing belt using the TDC method on #1 cylinder, and im getting a blue/white spark when i checked the plugs/wires for ignition. Only thing i havent done yet, is get the exact fuel pressure reading, its definitely getting fuel (smells like raw fuel when i turn it over) but im still rigging up a gauge to fit on the line to get an exact reading. So after i do that i'll be totally stumped, and probably buying a new computer.

this is really frustrating and i keep hoping its something simple that i overlooked, but until i get this car up and running again i cant tear apart my other one , which i finally got the parts for /

Try this, when your turning the engine over to start it, put the gas pedal all the way to the floor. That'll shut the gas off, and only let air in. I might just be a simple heavy flooder.

just tried that, no change, testing fuel pressure today and if i dont get any leads from that then its going to my neighbor, he has alot of electrical/electronic troubleshooting experience :/

make sure ur go back get ur timeing mark centerd.. then set the crank to 45 TDC ... just read that in the toyota mainly less then 5 minutes ago.. when i was checking for something...

Update: after tossing a few new parts at it i finally got it going, turns out it was a bad coil, the ohm test didnt show it, and the pull&ground the plugs test showed the plugs sparking blue so for a while i ruled the coil out. Why the coil went bad at that time I don't know, i wasnt even working on that side of the motor .. Thats what threw me off in the first place because i thought i may have stretched one of the wires in the harness or something. Anyhow its good to go now no problems at all and thanks guys for your input.
