Eagle Not Starting, has fuel and spark, timing is good too.
« on: April 17, 2019, 12:06:35 PM »
Completely at a loss here. Car is a 4.2l automatic  I have replaced the starter, alternator, carbuerator,and  battery cables.

When I first replaced the carb, this thing fired right up and idled like a dream. No backfire or nothing, so im assuming timing is fine.


Even after doing this, the engine just cranks, and cranks, and cranks. Everyonce in awhile itll speed up and act like its about to start. Ive tried shooting starter fluid in it and even that wont start it. Ive looked in the carb and see a steady stream of fuel shoot out when I look. Pulled the plug wires and got good spark.  My battery cables were in horrible shape so I replaced them with 2 guage cable.

Same thing. Still over and over again just cranking. Ive seen other posts talking about the vacuum lines and some “solonoid” that could cause it. But I have zero clue where to check for that. The lines seem to all be connected too.

I assume by "steady stream of fuel" you mean coming from the accelerator pump when you move the throttle??   If its a a steady stream out of the venturis, carb is flooding (shouldn't see any fuel from the venturis).

Also, put a timing light on it while cranking.   If the timing chain skipped a few cogs (your description is a classic symptom of that), the timing mark will be way off somewhere other than where it should be.

Good luck.

its also possible youve flooded it real bad. Hold the throttle wide open for 30 seconds or so to air it out then crank it while still wide open.

honestly im clueless on carbs, this is my first ever one. I looked up a venturis and I believe that is what the fuel is shooting out of. But Im also curiuous about the timing light, ill try that first before I try and unflood it

I had something similar to this happen with my 80 wagon a few years ago and it ended up being that both my ECU and coil had gone out on me. Both are very easy to get and easy to replace at least for me they were just remember that when you are unplugging stuff you have to be very careful as the plastic connectors can tend to get a little brittle and break.

If It's cranking then the Neutral safety is ok. Check the wire at the starter solenoid to make sure you have 12 volts while cranking. Should be a yellow wire. Then check yellow wire at the ignition coil for 12 volts while cranking. If that's all good,  pull the cap off the distributor and see that the rotor is spinning while cranking. If that's good then like maddog says, look at ecu connections and maybe replacement.

yeah I just reread it myself and I initially thought it said no spark as well but after re-reading it I seen that you said you had good spark so yet timing being off would be my guess also.
