I'm trying to find an accurate test procedure for the power transister and the wave form module in the distributer. Anyone have any ideas?

for the power transistor..does the truck have spark..?

for the dizzy ..does the truck have spark ??

Yes the truck has spark, but it will not start.

if it has spark it is not a problem with the dizzy..

the truck will turn over but it will not start. Fuel pressure is good, and I have good spark. The ecu has codes 24 and 31 displayed.

do not worry about the 24 but the 31 is ecm..

it seems as if it is bad..

i sell them..

if you are interested send me the numbers of the top of your ecm and i will see if i have the one you need..

you can email me directly..
