1986 2M4 Hi, what would cause a long time to start but when it starts it works fine. - takes about 20 seconds or more to catch, will turn over fine, so bat not a problem - then starts and works fine and runs perfect.
Latest changes, I changed a heater core and I replaced an O2 sensor, but used the car right after that and it was fine. Drove it one night and it was fine then parked it and the next morning I didn't think it would start and then it did. I checked for spark and had loads, never checked for gas.
Fieros have 2 ways to start the car (run the fuel pump). The usual way is the relay behind the driver next to the air intake. The second way is a switch in the oil pressure sender. If the relay circuit is not working, the car will slowly build oil pressure to activate the oil pressure switch, but it takes a lot longer to do this.
When you turn the key on, listen for a fuel pump noise in the center console.....it is probably not running.

Yes I can hear it no problem. The last time I tried starting the car before I actually turned it over I turned the key ahead to activate the pump, done that 3 times and the car started normal. I never had a chance to try it again. I was thinking that it might be the fuel filter and thought about changing it but the car works too fine when it's going, so it's not that.
I may disconnect the fuel line from the filter and see if it pumps fuel right away. I should shoot out right away...corrrect?
In the meantime maybe the relay never actually worked those couple of times and that is why it took a long time to start. I will listen to pump on start up before I turn the car over.
Well here is the latest. Last night before I started the car I disconnected the gas line from the fuel filter and of course gas ran out of the filter and the line seemed full. I turned the key ahead 3 or 4 times and each time gas came out of the line. I hooked it back up and the car worked perfect after that. I tried 15 or 20 times turning the key ahead and you can hear the pump click in. I drove the car and parked it for a bit and the car started fine after that, I tried the car this morning and all was fine.
I guess it's one of those Fiero mystery things. I am going to change the filter again anyways and maybe there might have been a bit of dirt in the injector.
