Having a little issue with a non zook car but I was wondering what the difference is between these 3 coils.

BOSCH SU12, SU12R and GT40R

The last 2 are resistor style coils..

Apart from that... No idea.. What does a google search bring up?

[royce]

SU12 is a stock replacement type, GT40 is the sporty version

Would using the resitor type make any difference?

[royce]

what car?

[buzbox]

4AGE AE82 corolla

It was working last week, but now it aint. After seeing the state of the distributor cap I thought by replacing it would definitly fix it. Basically it was missing two electrodes in it.

This car has been fucked arount with that much it could be a number of things, so my process of elimination so far is, dizzy cap, rotor button, Next is Coil, fuel filter, fuel pump.

Any thoughts?

I wouldn't think a 4age would use any of those coils, but they will still work

an engine that isn't working needs no process of elimination, it needs to determine which of the basic 3 things an engine needs (fuel, spark, compression) isn't there and then figure out why

The battery is on charge tonight so I'll check for spark tommorow night but whats a good way to test the fuel pump?

[royce]

fuel coming out the return from the rail after the pressure reg

Test with a pressure gauge.
