HELP! I'm at my wits end. I have a 1990 2.3ltr carbureuted Amigo that
had an engine that had bad rings and was on its last legs. It ran fine
(except for the low compression/bellowing smoke coming out the
tailpipe) when I pulled the engine and replaced it with a low mile
2.3ltr motor. The truck fired up fine and ran good after its heart
transplant. http://www.automotiveforums/vbulleti...lies/smile.gif
The Amigo had about an hour of time on the newly installed motor when
it died at idle in front of the house. There is spark at the plugs. I
put some gas down the carburetor. Voila! It fired up for a few moments.
I thought, "Aha! Fuel pump." I replaced the pump with a spare one I
had. No luck. It does the same thing. I pulled the fuel line that
connects to the top of the carb and turned the motor over. The pump is
shooting out plenty of fuel. So I know the carb is getting gas. I have look at other forums/threads and see
issues with the alternator, and charge relay. I put some gas down the carb and fired up the Amigo up long enough to
take a voltage reading at the battery. The battery reads 12.3 VDC
before start and as the motor runs for a few moments the reading
changes to 13.8 VDC. Looks like the alternator is good. Anyone know how to check the relay with a DVM? I am at
a loss as to where to look next. Any help with this problem would be helpful.

Did you make sure the spark plugs are firing, all you have to do to check it is pull a plug turn the engine over with the pulled plug hooked up and look for a spark.

Its very simple, all an engine needs are 3 things and it will run, may not run great but will run none the less. Engine needs air, gas and spark. I guarentee your engine is getting air and you say its getting gas so whats left? the spark, I would make sure your coil pack is working properly. Find out and let me know
