Found the problem, but now have another problem...BAD LUCk for sure. The problem the whole time was that bolt on the harmonic balancer had come loose. In process of changing crank sensor and found bolt loose. Well I guess I have a spare fuel pump and coil. Module needed changing. My new...

DailyDrifter Not sure, when I drove it last my scanmaster wouldn't come on. Haven't checked that out yet. Before then though cars coolant temp was normal...When it first started, I thought I had picked up some bad gas because I had just filled it up. Since then tank has been drained, blown...

Did car have a missfire all the time or just after car had reached running temperature. I'm having the same problem. My problem comes after car has reached running temp. I've changed plugs, wires, ign module, coil, fuel pump, filter and car still doing same thing. plan on checking that...

Update....PLEASE HELP Car still has miss once car has been driven about 8-10 miles. I fired car up lastnight and let idle for about 10-15 minutes in garage thinking, hey I finally got this thing. Well, drove car tonight thinking I was going to meet my wife and kids to eat dinner. Got about...

decided to go out and check one more thing. when checking fire at connector where pump pig tail connects, I was doing it by jumping it thru prong at alternator. checked it again by turning ignition on (had fire). connected pump and nothing. more info: this is a hp walbro, new out of box...

just installed new pump, direct plug in and pump is not running. checked fuses (good). hot wired at alternater and pump still not running, but can here relay click (twice). checked fire at relay and after (have fire at both). removed tank and pump. unpluged pump and checked fire at connector...

New coil and ign. module, is it possible one is a defect. When installing the module I made sure I tucked the prongs up so they would ground out. I just freshened engine up just over a year ago. Cam is new. Just alittle more history..Car was running fine until it would get about...

New plugs, wires, coil pack and module and car has started to cough when boost starts to come up. under normal driving conditions car seems to be running fine, cut if you get into it a little and boost reaches around 5#'s or so car will start to cough, spit. Car has a caspers hot wire...

I put scanmaster on RPM mode and spun car over, no rpm reading... this confirms that crank sensor is bad right.

I pulled #3 and #6 wires and spun engine over, no arc. I tried several different things, rechecking twires in module, making sure wires were right, checking fp relay, fuel pump pumping, fp and trying to crank engine after each check and could smell gas, if that means anything.

Just to catch everyone up..car would crank and run fine until it warmed up and would start missing and eventually shut down, not cranking until cooled down. First thing I did was change plugs, wires and coil pack. Well, I didn't get one of the connectors up and it shorted out causing modules...

Thanks for all the input. I have a friend with a module he's going to let my use and I'll know for sure...I'm thinking my module is shot by the sounds of it. thanks for the link, some good info

I think my module is fried and just want to make sure by asking some trained professionals. When I changed the coil pack, I noticed how sticky the clay is inside the module but didn't no any different. I installed the new coil and car still will not fire. Is the clay inside the module suppose...

O.K. I looked back thru the post and checked the fuel pump relay..found the male plug is melted, so it has definately gotten hot. So I know I need to replace it. What would cause relay to get that hot? Walbro fuel pump has less than 5000 miles on it. As far as cranking issue now, fuel...

New Problem after Coilpack Installation Installed new coilpack, plugs and wires...now car will not even try to start. Coil pack is on exactly how old unit come off. What could be wrong? Car was running before I did this, could I have a bad coilpack? The gum like material in the module is...

I'll be getting some plugs, wires, and a new coil pack. Thanks for all the help. Good to know about the plugs....

I went to get some plugs AC-CRr42's but I was told they no longer sale/make them. What is the best plug to buy? (20-25#'s of boost) I know coil pack is plenty hot (nailed me the other night), when I got home with car after one of it's missing episodes. I pulled each wire off one by one...

I thought I had a water problem, but not really sure now. I drained tank, changed two filters and now have new gas in car and car is still acting up. I can leave house and car runs fine, after about 5 miles car will pick up a miss and eventually shut itself down. Once car cools off alittle...

mid to top of 2nd gear, car is falling on its face. the only tuning system I have is a scanmaster and stock digital tach in dash. I plan on hooking a tach up to see what car is doing. Car is pulling really good until... and then falls a little just before going into 3rd and then pulls good...

I got gas a while back and just down the road car started missing and could barely run, limped it to the house to remove gas from tank finding some water, changed filter and haven't got gas from that station since. Car ran fine a couple of trips out and started stumbling again just the other...
