94 3.8 cranks no start

[billheb]

Brand new here so hello,
I researched for an hour before i posted this.I found a guy back in 2006 named serioussn95 who had the same problem.94 3.8 5 speed,38 lbs of fuel pressure,spark tester shows its firing,new plugs,new wires,new crank sensor,Its one of those family freebie jobs and the shop she had it at replaced all this and it still doesnt run.I replaced the plugs again myself and fixed the firing order on the wires.I almost forgot to say the engine back fires through the intake.Its almost like it tries to start running the same speed as the starter motor but when you release the key from start to run it dies.Id appreciate any suggestions.thanks

have you done a compression test ? and does it have passive anti theft , if so something might be up with it , if the PATS is messed up it will have spark will cranking but will die in the run position ......

no start

Thanks 2002blgt,
How does the pats system control the no start?Does it interrupt the spark or fuel?I worked for a dealer untill 1995 intill I went to the Louisville assemblt plant.I build fords now.My memory is pretty rusty after being away for 12 years.I was working on the assumption that pats came after 1994.thaks,ill check that out.

I dont remember what year they started , just an idea to try ....bad ignition switch down on the steering column could be messed up as well

Did you check the firing order at the coil pack? That caught me once...

95 3.8

I have the same problem with my 95 V6 right now. I have tracked down the problem to the injectors not firing. The injectors are controlled by the cam position sensor. I have replaced it but it still just cranks. This leads me to beleive there is a bad ground some where. Anyone know where to start looking?

have you checked for power to the coils and the injectors with the key off??

i don't think 94s had PATS, they had an optional active alarm but not a passive on.

do you have spark??

do you have injector pulse??

do you have positive power at injectors??

what's the fuel pressure??

what's the battery voltage while cranking??
