I have a 89 max, fuel inj., car does not run, at first it would
start and run cold but after warming up would not start, i checked
fuel pressure, had 40 psi at key on, replaced coil, module,cap rotor
had timming belt replaced 3000 miles back still comes up on TDC,
did dignostic on ecu showed no codes, has spark at plugs not real
blue in color, and spark is not consistent. thinking its a bad ECU
engine will turn over with startrer, has new exhaust system 3000
ago

 

try crankshaft positioning sensor

 

ok, I try that next, is this locatde in the distrbtor like a pick up coil?

 

What do the plugs look like?

 

I replaced them during this problem, old set was dry and
no oil present on plugs replaced with V- Grove ngk

 

were they white? black? grey?
I'm only refering to the tips of them here.

 

They were white to gray, looked a little lean on the cramic part.

 

do your o2 sensor if it hasn't been done within the last 30k.

 

Just testing control module with meter according to chiltons manual,
both old and new check the same which is bad according to the manual,
I have no counity between a & B , a & c a=+ lead on meter
I have counity between a & b , a & c A= - lead on meter
is this the correct way to check?

I thought the o2 sensor would only make it run rough, this thing
will not run at all.

 

This was the problem, it is located inside the distribtor.
I've never had one work part of the time then quit like this one.
The shaft int dist. had rough places that were tight to turn,
like ti was trying to seeze up. It runs again.
