Swapped 325e to i no crank

[delatlanta1281]

Did you switch the impulse sensor connector with the crank position sensor connector by the thermostat housing? Almost EVERY time something like this happens with an I engine install, this is the culprit. Even if you think you did it right, take 2 minutes and switch the two.

coil pack is good
wire from coil pack is good
12v into distributor cap is good
12v on rotor is good
but I am not getting 12v when rotor passes over individual post inside cap.
I assume that means its a bad cap?correct

If you are getting 12Volts at the distributor cap you have a problem somewhere else, most likley the coil.

wait so now it cranks or?
did you swap over the toothed crank pulley?

[jo3y]

i would bet its your CPS

[Jahman093]

squidmaster-yes it is cranking now. yes the toothed crank pulley was swapped over as well.

jo3y- would a bad cps cause it not to start or have spark?

A bad CPS will result in no spark.

[Jahman093]

Do you happen to know the ohm range it should have?

[Jahman093]

alright guys i am really stumped right now.
i have fuel but still no spark. i just changed the cps and still nothing. What else could cause no spark

[jo3y]

an improper air gap on your CPS, a bad coil, bad grounds.

off topic... i used to live in lakeland, small world

[Jahman093]

Grounds are good, replaced cps, and im getting 12v at coil. I am completely stumped :/

[jo3y]

what is the gap between your CPS and your trigger wheel. If that gap isnt correct the sensor cannot pick up the trigger wheel

[Alpine 7even]

Have you double checked that when the find tdc on the crank wheel, your cam gear is also at tdc? Timing is everything.

Did you try this? Its easy to get the two confused.

he is right. you need to check this out asap. before you throw anymore money into what could be an easy fix.

[Jahman093]

The gap between the cps and crank is .040. Before i put the engine in i replaced the timing belt and made sure both camshaft and crankshaft were at tdc. I have switched the two connectors.
I have been looking into checking the dme pins for power and continuity as seen in this thread http://forums.bimmerforums.com/forum....php?t=1487148

I checked everything that it said to do in this thread and it all checked out good.
