1990 dodge d150 ignition problems
Hi folks,
I am new so be patient. my problem is: I just bought this dodge ram d150 and i'm already having problems. the truck will be going down the road fine when it will just shut off.I try to start it and it will not start. I'll try a few times then all of a sudden it will start I took this truck to the mechanic and they said that the distributor was at fault. so after 600.00 bucks I get the truck back and it does the same thing. I check for spark at the plug no spark,I check for spark at the coil no spark. ten minutes later the truck will start and run fine. what can I check next? asd,pcm? where does the power to the coil come from? is it routed through the powertrain control module? or does it come directly from the battery through another relay? Help plz. I like this truck but am not going to sink a fortune in it

Thanks guys for the reply.
I went back to the mechanic its in the shop again.originally he
said that there was a problem with the hall effect pickup. but my
thing is if there is no spark to the distributor then the hall effect
pickup would show a code right?.I think instead tracking the problem he went for the first trouble code and replaced the
distributor. these guys are usually good at the electronics.

im fairly certain that a bad hall effect sensor should throw a code 11 (no crank/ignition reference signal detected during engine cranking)
by the way some shop manuals give a different explanation for that code.
anyhow just do the old onoffonoffonoffflash check.
and like moparborn says, 600 bucksis real money.

My truck did this to where it would start only in the afternoon around 3:00, try in the morning and it would just crank. Ended up being the computer was fried. Also since the computer was screwed, it wouldn't show any codes, the conventional way and with a scanner.
