So let's assume you have spark, have you check fuel pressure at the rails. That's what I would try next


No i don't even got a spark.


The fuel pump will hum and engine act's like it wants to turn over but no start.

Ok thank you for trying to help.


Ok I need you to check if you have voltage going to the coil, if not check your fuses. If you have the 12 volts then there is a coil under the distributor I gave a feeling this iis no good. But before you do anything make sure you have 12 volts at the battery. Ok im going to bed im old and tired,

Try the alternator, that's what was wrong with mine. Might be worth a shot


I have 12volts at battery and replaced the coil, plugs, plug wires and distributor cap. As well as the ignition switch. Still no start. It cranks and cranks but wont start i sprayed the lift with starter fluid and it still didn't start.


I checked all the relays and they seem to be getting volts/current. Anyone out there have any idea please let me know. I have put over $280 into my car in the past week and I still can't get it to start.


So i figured out why the car wouldn't start. My timing belt had broken. So after pulling apart most of the front of the engine i was able to find the problem buy a new belt for under $20 and replace it. Once put all back together the 1990 Geo Prizim with over 223,000 miles started up like a champ on the first try. It was a sound of success. Thank you all for your help and if anyone has a similar situation in the future check your timing belt first before you buy parts that cant be returned.
