Hard hot start. ecu?maf?FI rings?sensors?

[Daaan]

I already searched.
I have problems starting my 1g after its been running for about 2 months now. When i try to start it, it sounds as if its running on 2-3 cyls, turns over for about 3-4 secs @ 500rpm and dies outWTF. If i turn the air con on so the fans activate, it will cool down and start faster. It starts 1st try no problem when its cold. PLEASE HELP ME

Heres a list of things i have replaced..
1. injectors
2. maf
3. fuel filter
4. vac lines
5. plugs
and probably more just cant remember.
thanks everyone.

Make sure you have the plugs gapped right and you have the spark plug wires set in the correct order so the coil pack is firing to the correct cylinders.

Thanks I will double check those. When it starts it will run great and drive good until i turn it off. If i turn it off, then turn in on right away it will fire up right away. when i let it sit for 2-3 min then try to start it will bog and die over and over again for about 3 mins. then it will start.

check temperature sensor and wires, fuel pump and Fuel Pressure Regulator

I suspect early signs of ecu.failure. The 1G ecu`s are temperature sensitive among other things, & I`ve seen this exact symptom in a 1G be solved by replacing the ecu . . .

the 1G ECU have many problems because the capacitors leaks. i have 4 ECU in my house. all have leaked Capacitors.

Does anyone know what resistance should show up on a voltmeter when i check the coolant temp sensor? and at what temp it should be for that voltage

And its been doing this since the last owner owned it too. So i was thinkin if it was the ecu i would think the caps would have leaked out enough to destroy the board already.

i'm working now in ECU and i take one picture... look trails corrosion inside (down) the capacitor and in the right (backside heatsink)

Yeah i had two ecus blow up on my last car, but befor they went there was a fish smell. Dont have the smell quite yet.. i'm hopin its not that.
