Question about 1991 Eagle Talon

No ecu signal to injector 1992 laser 2.0L

I have no ecu signal to injector, i changed the cam sensor, doesnt change anything. i have all my + voltage to ecu and all ground are good.
Can anyone help me out on this tricky one?? I suspect the ecu to be defect. Btw, i have fire for plug, only no injection time :(

Eng code p0016

P0016 fault is poor crank/cam correlation. In other words the signals the ECU is receiving from the crank and/or cam sensors isn't making any sense and this could be caused by bad cam timing, wiring, connectors or the ECU itself or by faulty sensors but as you have changed these, probably not.

How do i fix to get signal from ECU to feed 6 injectors, permanent 12v are their.

You'll need a repair-shop manual to troubleshoot the engine computer and components.
The computer takes input from the crank and cam sensors (if equipped) and grounds the injectors when needed.

Your car has both a crank and cam position sensor. First start with your crankshaft position sensor. It is located by the harmonic balancer on the front of the motor.

How resolve a P1336 DTC on a 2005 Ford Freestar

Do you have code P1336 and poor driveability (ie misfires, surging like the trans is drpopping in and out of overdrive). if so you may need to relearn the pcm?
Did you by any chance change the plugs and wires, did you also replace the coil? Also, did you bump or pull the connector for the camshaft postion sensor? Could be it's just coincodence and the sensor just went. Not 100% sure, but I beleive that the cam sensor is used in a sequential fuel injection system to tell the ECU when to turn on an individual fuel injector. If the ECU doesn't detect a signal from the cam sensor, it will default to a batch fire mode, where all 3 injectors on either side of the engine will fire simultaneously causing misfires?
If you can't reprogram the ecu replace the camshaft sensor.

No 5&4 injector dont work checked all wiring but vcm will not ground changed everthing cam &crank sensors vcm but can get them to fire through the scaner

If only 2 injectors will not operate, I would start by swapping the 2 injectors to another location and see if the problem persists. If it does, replace the injectors. If it continues on those specific cylinders, replace the ECU (engine control module). The ECU is what contains the "drivers" for the coils and injectors otherwise known as the ground circuit which is signaled by the CPS which you indicated you have already changed. Let me know what else I can do for you.

Check engine light came on, computer scan indicated the cam shaft sensor was bad, changed the cam shaft sensor 3 times and the engine is still studdering and trying to stall. now the computer scan is...

cam sensor it also linked to the crank sensor usually if the cam sensor fails around the same time the crank can become un synced with the replacement. or the new sensor is not the correct one, ie sensor from a 1998 model will sometimes work on a 2005 model if it has the same ecu fitted in the 2005 not the hole ecu but the chip. on the cam sensor there is say in some cases 3 poles positive feed negative and then signal. on all the poles there is a resistance between poles that the ecu reeds. it reads the voltage being used and the signal its receiving if one of these is wrong but it detects one of the readings being right it will think the other sensor is wrong. and thats a mis match. the resistance changes over time.

2 fuel injectors not working and I dont think the problem is the injectors. If the problem is not in the wires, what controls the injectors? 1990 chevy beretta GTZ 2.3L

what engine do you have? the 3.1 the injectors are all wired togther, so take a test light and check the plugs on all of your inj. use a separate ground to check the hot wires, then use a positive connection to check the ground wires. if you have power to all, it is probably the inj., the 2.0 is the same, the 2.2 or 2.4 may have a different inj system, but you can check the wires the same way. the different system works off of a cam sensor, but if it didnt work no inj would work at all. it then feeds into the ecm (car computer). but i bet its either a wire issue or a couple of bad inj.

chack and see if your security light is staying on if so then security is shutting down fire to injectors.
are you gettting spark? pcm needs to see a signal from cam sensor to fire injectors. also when you first cut key on you should see the injectors give an initial shot of fuel
