Crank, no start
Customer stated vehicle was operating under cruise control at 60 mph, engine light came on flashing and stabiltrack. Car stalled and customer got it to side of road where it would not restart. Customer left battery unhooked before having it towed here so no codes saved in system.
Verified no start condition, no codes have shown up in 2 days of checking it.
Can communicate with all systems.
Have crank signal and good waveform, scanner shows steady increase up to 300 rpm during cranking. Have spark.
Have 65 psi fuel pressure, have injector pulse and also pulled injector rail to verify spray pattern.
Ran compression, 170-180 across all 4 cylinders.
Checked throttle body for correct operation, no problem found.
Checked catalytic converter, even unbolted and inspected shell and with exhaust unhooked no difference in cranking.
Checked purge valve and found no issues.
Also worth noting that I have lots of spare parts for these cars so I swapped with a known good coil and spark plugs just to see if it made a difference. Car cranks strongly but will not actually start. Feel like I'm missing something really simple here.
a vehicle needs 5 things to start: - Air - Fuel - spark - The correct amount of each. - All 3 need to be occurring in the proper sequence(in time)
A quick thing you can try is just unplugging the MAF and see if it will start. You may already know this sometimes I forget the little things too
Hi Ted, Disable the fuel and clean the plugs then try running it on a propane torch/ bottle. This favors a contaminated fuel issue possibly.
Hi Ted, I have seen a lot of that this year, distributors are dumping reclaimed contaminated fuel off on many small stores these days. It is that or the car owner has some 3rd party mischief going on. Drop the tank and clean it out, there is no other way to resolve this issue.
I presume you checked all the fuses? Engine/Transmission oil levels good? Timing OK? Starting fluid in throttle body to see if it will even pop.
I see you swapped the coil and plugs but did you check for spark? I've seen a bad ground for coils or blown fuse cause the same symptoms. sorry i missed where you said you have spark
You pulled the injector rail? Thats quite a bit of work since its a DI vehicle. Did you use the proper special tools and replace the combustion seals. If you didn't, you created a new problem for yourself. In any event, what usually kills these cars is a rocker arm or two that comes off of its pivot. Compression will still look despite a valve isn't opening.
It's not really any work on this car, it's one nut and 2 t30 screws on the intake. I did change the seals out since they were removed. It ended up being a contaminated fuel issue.
Then you must have mis-listed the vehicle type in the description in your original post. You have it shown as a 1.4 LUV motor. Those are direct-injected and you can't just pull the injectors out. You need to use a slide hammer and a bunch of other special tools.
That's what I said earlier. “I'm confused” to be specific. And of course there was no VIN…
Hi Tony, I have brought this up with DN before along with asking for a mileage reading. Apparently it has not become important enough to them yet. Then again, I have seen people get defensive and think you were asking for their social security number when you ask for the VIN. It's like they are paranoid. Luckily, We don't have near the trolls or idiots like other sites yet, and I hope that…
The DN folks are very polite and give much more latitude than other sites. Nonsensical posts for help aren't called out with the bluntness that they deserve.
It says its a Limited Jeff which wpuld have the old port injected 1.4. He must have got the wromg engine RPO.
You pulled the fuel rails and verified spray pattern? I'm confused. This is a SIDI engine, correct? Have you verified the fuel high pressure PID is normal when cranking or that you have any high pressure operation beyond the electric in-tank pump's 65psi?
Couple of questions. Why was battery disconnected? How does that clear codes? Was a jump start attempted? Can you induce a code and then read it? The first two paragraphs have unanswered issues.
