No Spark. Car cranks, but no spark from ignition coil.

Yes, Timing belt and adjustment both good, ray

crank sensor? i forgot this engine had one.

Thanks for reply; Worked long weekend and am trying to test system again today; Have checked Crank sensor several times and do get proper resistance but will try to see if there is signal change while cranking; Previous tech dropped me after first reply so don't know how long you can stay with me, but do appreciate your help. Thanks, Ray

ill stay all the way to the end. check for ac voltage on crank sensor while cranking. it should have a fluctuating ac voltage

Electrical problem
1996 Toyota Camry 4 cyl Front Wheel Drive Automatic 189000 miles

My '96 Toyota Camry rolls over like a champ but has literally no spark. We've replaced the distributor, ignitor, fuse and relay boxes, relays, fuses, coil, and checked every inch of wiring under the hood by testing it. The crank sensor pulley and computer test out fine. There's fuel coming through but no spark to fire it up.

We've been fiddling with this thing for weeks and still no difference. Please, please, PLEASE someone help me. We're willing to try anything.

Thanks mucho! Checked Crank sensor connector unplugged from sensor and found no voltage on my digital meter with ignition on or while cranking( I am assuming voltage probably 1-2 volts) It seems I should have something from ecm to sensor? Have not checked same while connected; wires have tight rubber boot at plug. Ray

Did you check if the distributor turning as the engine cranking
check wiring harness

OK, I was able to back probe crank sensor connector while connected and saw 1.6 volts ac and did seem to fluctuate a bit; Tried same with igniter igt wire at connector and saw .01 to .02 and thought saw .05 1x. Now wondering if ecm not just right, or possibly the used igniter I tried is bad? Thanks, Ray

I've checked both but the wiring harness is golden. Every inch of it. And the distributor is spinning like a champ. This car is beating everything out of me...

senor cecks out ok. possible igniter problem. these trouble tree on this thing is so vague and most end up saying install known good part.

with key on do you have a check engine light on
if not replace EEC power relay

Where exactly is it located? I've replaced all the relays under the hood so I'm guessing it's some where else?

Never mind... We found it and it tests well. We even swapped it out with the fan relay because we know it works and there's still no spark.

Computer problem
1996 Toyota Camry 4 cyl Two Wheel Drive Automatic 250000 miles

Car stalled at hwy speed, was able to restart 1x with repeated cranking, stalled immediate and am now troubleshooting cold wiithout spark and code 1300; CPS, and pick-up sensor test within range as well as coil; Did try new coil, and 2nd igniter(used) with no result; Power at coil and igniter; Distributor turns freely; Have checked connections and all appear ok. Do have multimeter and test light ; Tested negative side of coil with light while cranking and saw only dim light, no pulse; Have not checked igniter plug for pulse; Pick-up sensor plug has 2 pin connector; Igniter outer wires w,wr I believe are igt and igf signal; Is it possible for me to get a good test for igt signal from plug? and also good test at pick-up plug to confirm voltage? Thanks, Ray

Hi
try these tests
Disconnect Black 5 pin igniter connector acess ECM behind glove box. With ignition on measure voltage between ground and term. # 3 white/red wire at ECM E 11 connector. Voltage should be 4.5 to 5.5V if not replace igniter if not replace ECM.
Next test Back probe trem. #20 white wire at ECM 11 and ground while cranking if voltage is not .1 to 4.5 replace ECM
Hope this helps
Thanks for donate

Thanks for prompt reply; I did check voltage at ECM with igniter connector unplugged and all else plugged and got 5V #3 and .6 #20 while cranking. All components under hood are OE and have not been able to check air gap on distr, as I do not have proper guage. Thanks, Ray

Hi Ray
Check for open or short to ground on these two circuits
IGF on ECM connector E12 terminal 3 white/red wire and IGF on igniter term 1
IGT on ECM connector E12 term 6 white wire and igniter term 2
Let me know
Check air gap with match book cover .012

Really appreciate your patience and help; Am I checking each circuit by test probing at disconnected ecm connector and to ground with igniter connected and battery disconnected? Feel air gap is within range; Do notice clicking sound while turning by hand but assume this is normal pu sound. Thanks Doc

Hi Ray,

Have you solved the problem?

Thanks for reply, No have not solved, still stumped; Did try rebuilt distr, no action; verified signal from crank sensor, igt voltage is very low? found ecm online with matching numbers and ordered but was cancelled, apparently not available now. Ray

Hi Ray, Sorry for the delay in replying. Yes, seems the ECM or its wiring is at fault. I do have the completed diagnostic procedures her, go through them again and see if you get any different results. DTC P1300 - IGNITER CIRCUIT MALFUNCTION CAUTION: If ECM replacement is instructed in following testing, always ensure ECM connectors and ground circuit are okay. If either are suspect, repair and repeat testing to confirm ECM malfunction. Circuit Description The ECM uses pick-up coil input signals to switch primary ignition circuit on and off. Primary circuit is turned off when ECM delivers a signal to igniter on the IGT wire, causing ignition coil to fire spark plug. After delivering a command to turn off primary circuit on IGT wire, the ECM monitors IGF circuit to ensure primary switching occurred. DTC is set when there is no IGF signal to ECM for 4 consecutive IGT signals during engine operation. Possible causes are: IGF or IGT open or short circuit from igniter to ECM. Igniter ECM Diagnosis & Repair 1. Check for spark at misfiring cylinder. If spark is present, go to next step. If spark is not present, go to step 4 . 2. Check for open or short in IGF circuit between ECM and igniter. Igniter is located near left shock tower. See appropriate wiring diagram in WIRING DIAGRAMS. Repair as necessary. If circuit is okay, go to next step. 3. Disconnect Black 5-pin igniter connector. Access ECM behind glove box. Turn ignition on. Measure voltage between ground and terminal No. 3 (White/Red wire) at ECM "E11" connector. See Fig. 3 . If voltage is 4.5-5.5 volts, replace igniter. If voltage is not 4.5-5.5 volts, replace ECM and retest.

4. Check for open or short in IGT circuit (White wire) between ECM and igniter. Repair as necessary. If circuit is okay, go to next step. 5. Access ECM behind glove box. Locate ECM "E11" connector. See Fig. 3 . Backprobing ECM connector, measure voltage between ground and terminal No. 20 (White wire) at ECM "E11" connector while cranking engine. If voltage is .1-4.5 volts, go to next step. If voltage is not .1-4.5 volts, replace ECM and retest. 6. Disconnect Black 5-pin igniter connector. Backprobing ECM connector, measure voltage between ground and terminal No. 20 (White wire) at ECM "E11" connector while cranking engine. If voltage is .1-4.5 volts, go to next step. If voltage is not .1-4.5 volts, replace ECM and retest. 7. Turn ignition on. Measure voltage between ground and terminal No. 3 (White/Red wire) at igniter wiring harness connector. See Fig. 8 . If voltage is 9-14 volts, go to next step. If voltage is not 9- 14 volts, check and repair igniter power source circuit. See appropriate wiring diagram in WIRING DIAGRAMS article.

8. Check for an open or short in wiring harness between ignition switch and ignition coil, and between ignition coil and igniter. Repair as necessary. If wiring is okay, go to next step. 9. Check ignition coil. See IGNITION CHECKS (DISTRIBUTOR TYPE IGNITION SYSTEM) in BASIC TESTING - 2.2L article. Replace coil as necessary. If coil is okay, replace igniter.

installed new timing belt b4 it ran well now it is not getting spark it wont start

Check the ignition fuse and good connection at the distributor/harness

Wanted to thank you for your followup; Finally received reconditioned ecm, and did solve the problem; Car started immediate and runs very well at 251k miles. Wonder if Washington really knows what happens on mainstreet? Ray

no power at distrbutor test light says so
where is fuse? how many amps?
before timing belt job, ran great how can this go bad
unless something was not plugged back together

Hi Ray,

Thanks for the input and glad you have solved your problem.

If Washington knows what is happening on mainstreet, what can or would they do? ;)

Have a nice day.

Check the white and red wire at the ignitor and injector do you have power ? No power at the coil/ignitor/injectors points to the igniton switch and AM2 fuse 30amp at J/B2 left front fender

sorry, i have power at the coil the car ran perfect before timing belt install thanks ans i ll let u know night here now

WHAT IS WRONG WHEN THERE IS NO SPARK ON THE SPARKPLUG?

Hi there,

With these early Camry's it is usually a faulty coil which is in the distributor,but a scan is a good place to start, start here.

1996 Toyota Camry 4 cyl Front Wheel Drive Automatic 149000 miles

all of a sudden while i was driving the car shake and stopped and never start again. i change the ignition coil, the rotor and distributer cap but nothing. the mechanic examine the car and he said there is no electricity gose to the sparking plug. so your help please.

No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,coil's resistances,cap and rotor /distributor pick-up coil, ignition control module, ECM,Ignitor cam and crank sensors- Note: If it doesn't apply disregard it

i have no spark. spend the last week going through forums and trying every test procedure i could find. no results. plz help

scan for codes first se if you are getting any and try resetting anti theft on car if it has it
