coyote kid Posted January 18, 2014 Posted January 18, 2014 I am building a custom dash because mine is nasty I removed the dash and the whole climate control system now it just cranks and cranks but no fire seems to not be getting spark ... Are there any grounds or wires that need to be connected in the dash in order to run is there a way to wire your own ignition system ?
coyote kid Posted January 18, 2014 Author Posted January 18, 2014 I also removed the head to do a head gasket if that helps
MJ_Milam Posted January 18, 2014 Posted January 18, 2014 need more info. what did u do first? i would start with head gasket. start with basics. check compression. possibly incorrect adjustment valve adjustment. is it a 4 or 6 cylinder?
coyote kid Posted January 18, 2014 Author Posted January 18, 2014 2.5 4 banger I didn't think you could adjust the valves on these ?
Eagle Posted January 18, 2014 Posted January 18, 2014 2.5 4 banger I didn't think you could adjust the valves on these ? You can't -- they're hydraulic. Why do you "think" you're not getting spark? It's easy to check, so check. An internal (some would say "infernal") combustion engine only needs three things to run: Fuel, air, and spark. Take away one of the three and you have a problem. Spark is easy to check, so verify. Either you have spark -- or you don't. Did you remove the distributor from the block when doing the head gasket?
MJ_Milam Posted January 18, 2014 Posted January 18, 2014 sorry i was thinking theyre like a chevy where you zero lash them amd do a full turn
coyote kid Posted January 18, 2014 Author Posted January 18, 2014 I did not remove the distributer but I did remove the cap however I marked it with tape so I lined it back up I know its getting fuel plugs are wet
MJ_Milam Posted January 18, 2014 Posted January 18, 2014 did you hook the ground strap from the cylinder head to the firewall? just thinking of simple things first
coyote kid Posted January 18, 2014 Author Posted January 18, 2014 yep no luck and what electronics on the motor itself are required for spark
carnuck Posted January 18, 2014 Posted January 18, 2014 If the head is still off, it won't start..... just sayin!
gogmorgo Posted January 18, 2014 Posted January 18, 2014 Most of the engine controls, particularly the ignition system (i.e. spark) runs through the ignition switch, which is in the dash. If that's not hooked up and everything else is, you'll be able to crank it by turning the key, but it'll never fire.
coyote kid Posted January 18, 2014 Author Posted January 18, 2014 Can I wire my own ignition system ? I have had nothing but bad luck with this things wiring because the po hacked up the harness after a packrat problem and never labeled anything
Eagle Posted January 18, 2014 Posted January 18, 2014 Can I wire my own ignition system ? I have had nothing but bad luck with this things wiring because the po hacked up the harness after a packrat problem and never labeled anything DO YOU HAVE SPARK? HAVE YOU CHECKED?
coyote kid Posted January 18, 2014 Author Posted January 18, 2014 When I checked this morning no it did not I got it to backfireout of the throttle body onice but that's it
Eagle Posted January 19, 2014 Posted January 19, 2014 After the backfire no spark No spark -- or no start? Have you removed a spark plug wire from the spark plug, and held it (carefully!) near a solid part of the engine while cranking to see if a spark jumps from the wire to the block? Have you removed the coil-to-distributor wire from the distributor, put a screwdriver into the terminal at the end of the wire, and then checked to see if there's a spark between the screwdriver and the distributor cap terminal? In other words ... HOW have you determined that there's no spark?
coyote kid Posted January 19, 2014 Author Posted January 19, 2014 OK well I feel retarted aparintly when I put the cap back on the dizzy I didn't put the rotor on as I found it under the jeep .... So I put it back on and bam she runs ! No more overheating too !
Eagle Posted January 19, 2014 Posted January 19, 2014 OK well I feel retarted aparintly when I put the cap back on the dizzy I didn't put the rotor on as I found it under the jeep .... So I put it back on and bam she runs ! No more overheating too ! That'll do it. Glad you got it fixed.
Elijah808 Posted January 27, 2014 Posted January 27, 2014 I'm having a spark problem too. No spark but it turns over
Eagle Posted January 27, 2014 Posted January 27, 2014 I'm having a spark problem too. No spark but it turns over Year? Engine? Could be CPS. Could be coil. Could be ignition module. Could be ECU. Could be wiring (especially if you have the C101 connector on the firewall) What have you tested so far, and how?
