Are there any common ignition problems/issues that I need to be aware about?

I just had my 88 4.0 towed home and I suspect it's ignition related. The fuel rail is pressurizing so that narrows it down quite a bit. Possible computer failed maybe?

Where is a good place to start my troubleshooting hunt?

 

Btw, all the car does is turn over with no fire at all. Also, I have been noticing that it's been taking longer to fire lately; maybe that'll help you guys narrow down my possible issue.

cps is the most likely culprit they go bad quite frequently and cause this situation also check for spark check the coil plugs wires and whatnot

 

Yup, that's what I was thinking too. I found this too, it helped a lot!

I had that problem during the winter parked it, and the next day it would not start. Changed the plugs and the fuel filter still nothing. Then after about a week of sitting in my driveway I went outside to start it and it started. Its ran fine since then.

 

Sounds like your CPS is going bad too. Its definately something that Ill remember to replace every 100k miles just to be safe; like an o2 sensor.
