My 96 80, 1fZ will start but won’t stay running. So last week I had to replace a ruptured heater hose. The one under the intake manifold and above the starter. I didn’t want to remove the intake so I worked underneath. I’m a big guy and struggled immensely to get in there. I removed the starter and quite a few other things to get it done. I was careful to get everything back together the way it was. When I went to start it it cranked fine, but no start. I checked the ignition system and there was no spark at the coil. I replaced the crank position sensor but still no luck. I discovered the neg. battery cable was trashed. I replaced the cables and several ground wires and it started! It ran for about 1/2 an hour then shut it off. When I test drove it it shut down half a block away. Now it will occasionally fire but will shut down as if I flipped a switch. When this happens everything else still has power. Some things that come to mind now is perhaps a bad coil. Another thing is maybe the fusable link, however it’s only about 6 months old. I did notice that the link that has the grey plastic plug had been replaced on the harness side. It has shrink tubing but I don’t know if it had been soldered or crimped. I discovered last night that there is an ignition control module that potentially could cause these symptoms, anyone have problems with that? It’s about $200 so I hesitate to just buy one to try it. I sure could use some help, this is my daily driver. Thanks.
