Hello yall,

I have an 89 bronco 2 2.9l v6 and today all the sudden it stopped..it will turn over no problem but will not.start. I have no idea whats wrong .. after awhile of trying to figure it out it started but then the rpms went low and it shut off..please help me!!

 

Did you check for fuel? Spark?

 

Yea..put a new fuel pump in..still doesn't work...how can I tell if its the spark plugs? I'm stumped

 

A new fuel pump is only part of the fuel system. Does this new pump run? Have you checked the fuel pressure? Can you hear the fuel injectors firing?

For checking spark, I like to use my old inductive timing light to indicate whether something is getting through to the spark plugs. You could also pull a wire, hook it up to an old plug, hold it/rest it against the block and see if it fires.

I might also pull codes, as some causes for a no start will leave clues in CM (like a CM 14/18 could point to a faulty TFI module).

 

Well I'm not getting spark from the spark plugs not the ignition coil..plus I'm geting 12v off the ground of the coil so I'm just guna test the coil

 

Did your bronco ll sound like it was running out of gas before it died. It might be the ignition module on the distributor. Also check all the wires on the electrical connections I had a 84 that lost spark and it ended up being the positive wire that plugs into the coil. You might have to dig into the wiring harness from the module to the coil,and continuity test all the wires. Also you can use a inline spark tester for spark checking,I like these because you can see if there is a erradic spark. just a couple of things to check.

 

Also if all the stuff you try doesn't work don't rule out a bad stator in the distributor. My 87 that I bought ran great but sometimes ,(usually when I was at a store paking lot) it would not start . I had to wait for it to completly cool-down then it would start. Until one time it just wouldn't start. so if you have experienced this you might want to replace the whole distributor. I got a lifetime warranty one at an auto parts store for less than $60. The hardest part of putting in the distributor is putting the hold-down bolt in I have big hands and there isn't alot of room back there. so maybe have a magnet or a spare bolt on hand

 

buy you a spark tester. It plugs in to your plug wire and plugs to your spark plug

 

This may not be your problem, and I don't really know much at all, but I recently had a similar thing happen to my Ford ranger. It started and then RPMs dropped and it shut off. Would turn over but wouldn't start again. Replaced the alternator and it's all good now
