No fire from coil- replace crank sensor, fuel pump relay , new spark plugs


If you have fire going into coil and not coming out than replace coil pack. They can become weak and will cause firing to be muted. Coil should read about 13ohms with an electrical tester when disengaged from the cars power supply set on 20+ohms. Anything less needs replacement.

Why car my car start?


No spark? Then there is probably no signal to trigger the spark. Possible causes:
1) Cam position sensor.
2) Crank position sensor (you replaced it)
3) Coils (already replaced)
3) Wiring and connections to and from coils (bad grounding points or bad live feeds)

Suggestion: Stop the guessing and spending with "probable" causes. Have the car scannned for error codes and start from scratch according to error codes.

No spark from ignition coil to start the engine of suzuki vitara16v EFI engine. what is the cause of it


what year? what country? sounds like suzuki G16b engine. is it? or 2.0L?
The reasons are the same basically for G16 or the 2.0L
Both engines have ECU.
Both need good fuses to power ECU and coils.
Both engines need working CMP.
my guess is this is a distributor engien G16b (YOU SAND COIL NOT COILS.)
1: fuses, test the fuses relate to ECM/PCM (3 fuses)
CEL LAMP MUST BE ON KEY ON OR ECU HAS NO POWER.
2: g16B( CRANK FOR 5 seconds), with scan tool connected.
A $50 tool that is indispensable.
P0355 or P340 DTC , bingo, no spark.
or while cranking RPM is dead at 0 RPM.
if all that passes, then check the coil signals. (@ minus term)
The coil has an ignitor in the dizzy and both can go bad.
recap.
power 12v to ECU
CMP working
ECu sees CMP and sends spark to dizzy ignitor.
Ignitor , drives coil, coil makes spark ,engine runs.

Power to red wire on coil no power to distributor wires


Yes the crank sensor could keep the coil from firing, but your truck does not use a crank sensor assuming its a V8.
The coil gets power from the key switch, and the ignition module inside the distributor grounds the coil to fire it.
So the problem could be the coil, or the module or pickup in the distributor. The pickup coil in the bottom of the distributor acts as a cam and crank sensor.
You may need a repair book or shop manual to get the test procedures.

po700 code just means you have codes
P0351-IGNITION COIL #1 PRIMARY CIRCUIT

WHEN MONITORED
With battery voltage greater than 8 volts during engine cranking or greater than 13 volts with engine running. Engine RPM less than 3000. No coil in dwell during test.

SET CONDITION
Peak current is not achieved with battery based dwell plus 1.5 msec of diagnostic offset. It takes less than 3 seconds during cranking or up to 6 seconds while running to set.

POSSIBLE CAUSES
- Ignition coil
- Intermittent condition
- ASD relay output circuit
- Ignition coil driver circuit open
- Ignition coil driver circuit shorted to ground
- PCM

Car runs for 30 min and then dies ,will run after sitting for 20 min is that the crank position sensor


Not the crank sensor. It is the coil. Coils are nothing but a coil of copper wire. When the heat comes up the copper wire expands and causes the wire to come apart. When it cools it shrinks back and the car will start again.

I have no power coming out of my coil. Is it the


Might be.

Coil is controlled by ground, not power, so you are describing a normal condition.

The crank sensor is a common cause of a "no spark" condition on these vehicles. Other things can cause the same problem though.

'96 Dodge Dakota will crank, but won't run.


a bad crank sensor or dist pickup plate can cause this.... check the fuses in the fuse block under the hood for any blown ..... a bad auto shut down relay may cause it .....try putting a test light on the green and orange wire and see if it lights up when you try to crank it
