Car shuts off while driving ??, Problem solved.... Options

[Remy]

Hi, I dunno what could cause a car to just shut itself off while driving ?? Happened to me twice now so I know thiers something wrong the first time it happend thank god their was no car around the second time will lets just say the person behind me was paying attention or else I would be making a "totaled celica" thread.

When it turns off it feels like someone switched the key to off/on and you see all the brake,oil light, and check engine lights. The second time it made a popping noise before it shut-off the first time it felt like the car just stalled while going 40mph.

I'm not sure whats causing this but I know I just replaced the distributor with a new one checked my plugs and wire haven't had time to check anything else but was hoping someone had this problem before and can help me diagnose this fast. Thanks.

I was thinking ignition switch but want to hear what you guys have to say too.

The codes it threw were 1-2 and 1-3 so I think I have a bad ECU....

when it happened to me it was the efi fuse - thats after replacing distributor/ignitor/checking fuel pump/ ecu everything try that

I checked that fuse and all the other they're all working fine. Thanks for input.

i had the same problem , car would cut off randomly pulling up to stop lights. then it got to where it wouldnt start randomly some mornings, just progressively worse over time. idle was fairly low also, new ecu fixed it. good luck

I hope the new/used ecu would do the trick Thanks.

does it fire back up immediately or crank sputter then catch and run?

It won't start right back up it kinda crank sputters then starts when it does.

sounds like possibly a fuel pump going bad then, next time it dies cycle the key a few times and start it. if then it fires up immediately then i'd bank on fuel pump problem, hook up a fuel pressure tester and try to get it to die in the driveway to confirm....or just throw a pump at it and cross your fingers.

I jumped terminals B+ and FP I'm getting fuel pumped through the hoses so my Fuel pump is working.

make sure your ignigter is plugged in properly. If it came loose in any way it would cause this.

I also checked the ignitor and connections they're on nice and snug.


Well now the car won't even start it'll turn over but won't start and the only codes I'm getting is 1-2 ECU not getting signal, so the last thing on the list is the ECU. I'm currently taking the ECU out for testing but though I'd give you guys an update. Oh and I also bought some NGK laser plugs since one of the heads of my old plugs (Denso) was spinning put still no start so that wasn't the problem. Thanks for the advice/inputs so far everyone.
