Car ran fine all day. Turned off car for an hour or so and tried to restart. Idled fine but then started to bog down when trying to accelerate. Now car won't start/idle. Checked fuel pump, spark, timing belts, fuses and those all functioned properly. Up until now I had a 85 GL with a Weber and am new to SPFI. Thoughts or input? Thanks!

 

Edit. Got up this morning connected the white plugs under the hood and pulled 2 codes. 14 and 21.

So I popped the intake boot off and can still see the injector cycling fuel into the throttle body.

Check for spark at the plugs.  That happened to me,  turned out to be bad coil wire, that looked OK when tested at the coil, but didn't work when connected to the distributor, plug wires and spark plugs.

I pulled a spark plug, grounded it out and have spark. Im just at a loss on where to go next. I checked the timing belts they dont look like theyve skipped a tooth at all.

Code 14 is fuel injector abnormal output.

21 is water temp sensor open or shorted.

That would do it. It is the 2 wire sensor under the thermostat. Screws into the casting.

I picked up a CTS out of a Junkyard and put it in this morning. Still no Change. While cranking the engine today right as I let off the key it sounded like it fired on a single cylinder.

 

Anybody have any other ideas?

Have you tried cranking with the gas pedal floored?  This is the clear a flooded engine procedure.  I've had a few mysterious instances when one of mine died, wouldn't start, and this cleared it.  It takes a fair amount of cranking.

 

Related test - spray a second or 2 of carb cleaner into the intake boot through one of the smaller lines [pull off, and replace to do it]

Try cranking with gas pedal part way down.  If it fires and runs for a burst, you have spark and timing.

 

 

If you have an ohmmeter, you can [and should] test the CTS, especially a used one.
