Here's my dilemma. Most of my motor is new, most, but not all. Wednesday morning I let it idle for about 10 or 15 minutes, went and put in 3.946 gals of gas (The reason I say this is that my X1 tank is 4.1 gals give or take so I thought it may be bad gas). Left the gas station and rode maybe 2 or 3 miles and went to meet another rider at another gas station. When I pulled in the bike stalled and never started again. It acts like it wants to but will not start. Once home I pulled the timing cover off and all was good. I disconnected the fuel hose just before the filter and ran it into a glass jar, cycled the fuel pump a few times and it looked good. I didn't taste it but it looked good  How do you test bad gas anyway? I'm getting spark, I've got compression but I've not tested the electrical system but that may be my next step. What do you guys think, what will I be doing in the garage tonight? BTW, on my way to the gas station and after it ran strong, no burps, hiccups or anything, just strong and steady. Then pulling into station no. 2 it just quit and no more nothin'. | ||

crap in the fuel filter and injectors | ||

Yeah, I thought about that. I'll be a big hypocrite if it's the injectors. I've often told people to spring for new injectors when it's that far torn down then I went and put my old ones back in. Serves me right I guess. Isn't there a Ford part that's the same injector? Maybe it was Pontiac. | ||

I think it's Ford, but not sure (all our tubers are carb). If you have a friend who wrenches on cars, borrow some EFI noid lights - they plug into the injector harness and have a light bulb that lights every time the injector would fire. Helps narrow it down. I just went thru it on a 4.0 Jeep we own. On the Jeep, there are 2 ignition sensors - one pickup in the distributor, and a crank sensor. Distributor pickup going bad, just no spark. Crank sensor bad, no injector pulse. Noid light told me no injector pulse - of course. The crank sensor is a bitch to replace in a parking lot with the wrong tools...lol. | ||

Kyrocket: This fuell injection parts are off cars ... O2 sensor, Injectors, and "i" do not know what else !!! With the PART NUMBER off the unit a sharp PARTS PERSON can tell you how many CAGE'S it is used on ... | ||

I would check fuel pressure also,was having starting problems like yours in the spring.pump was good,regulator was bad. | ||
| Kyrocket |
I've been doing some regulator searches... I just came out of the garage and after running the battery down I hooked it up to the car battery. I can get it started if I slightly crack the throttle and keep it between 2 and 3K RPM's but anything over that and it bogs down and backfires, almost like it's starving for fuel. I'm beat, I'll tear down more tomorrow. Thanks for the info. | ||

Mine did the same thing, the problem ended up being the computer. I had almost no injector pulse. The dealer couldn't even figure it out. I switched to a carb. | ||

hey! that's the throttle shaft! Mine did exactly that when the brass shaft in the throttle body broke. The cables are attached to one side and the TPS is on the other side. It's only working right if you open the throat just right. I got mine home running like that  | ||
| Kyrocket |
Thanks for all the info. I'm hoping to be able to spend some quality time with it tonight and diagnose the problem. I'd never thought about it being the ECM but I still have the original under the house somewhere in a box. I may have to dig it out. Nate, what and how exactly did you decide that was it and then ultimately fix it? I hate taking off the bread box backing plate. Just seems so tedious. | ||
| Natexlh1000 |
Take a look in the throttle body. they break near one of the screw holes on the shaft that holds the throttle plate. once you can get your face in there, it's easy to see if my theory is right or wrong. If your shaft has popped, the throttle body assembly is under $100 and comes with a new TPS already on it. I have a forcewinder and no side panels on mine so it was very easy for me to get at it all. | ||

Throttle shaft nope. Regulator nope. Coil nope. Now it seems I'm not even getting spark, well, just intermittently at best. Plug wires have some age on them so they could be a culprit but both going at the same time doesn't seem right. My battery is checking in at only 11.9 volts which should spark but I'm taking it to the shop tomorrow just to be sure. I just purchased it this summer but I want to make sure that's not the problem. | ||
| Kyrocket |
I may have jumped the gun on the coil. IF I'm testing it right it's bad. Should be checking in between 5 and 7.5K but it's coming in at 11.5 way out of it's parameters. Wish someone close had a good one so I could check it that way. Hate to drop $100 just to find out I checked it wrong. |
