Mr2 Turbo Wont Start

[IMPORTMyth01]

Whats up tn, I have a 91 mr2 and it ran fine till the other day i took a ride to the parts store and it started sputtering and breaking up real bad like it was running on 2 cylinders. Then I shut it off came back out of the store and it cranked right up, 2 seconds later it just died. I replaced the battery and checked everything but I cant seem to find anything wrong, it will crank over but wont start???? anyone have the same problem? any help will be appreciated, thanks

Im thinking its maybe my coil and igniter??? ECU is throwing no codes and there is no spark going to the sparkplug wires...how often do coil's and igniters go out??? or can it be a main fuse somewhere??Thanks

Yeah i had a kind of the same problem but mine happen in the rain, I'd say see if the Am2 fuse under the hood is blown that what was wrong with mine.

yup, check the easy ones first like the fuses and ignition main relay(located in fuse box in engine compartment driver side, check ecu-ig 7.5A fuse as well. am2(7.5A), am2 H(40A) fuses located in front trunk fuse box passenger side.

if its not your fuses.. check for a spark. if you do have a spark then its not your coil or ingniter, also it could be your alternator.
Do you have a cone type filter ? or factory air box.
because if you do have a cone make sure you have a bracket to keep it leveled otherwise u wont get air in the engine and it will rich it up.

good luck

i dont have any spark even going to the coil...how would I check the coi and igniter box???my alternator is brand new and starter is also, if the fuses are bad will that cause it to not even spark?? thanks

i have a cone filter and it is held up by 2 brackets and its pretty level

i found the problem i had a couple of bad connections in my wiring harness...anyone know a good site that can give me all of the wiring diagrams for a 91 toyota mr2 turbo??? thanks
