no spark...evo 7

story goes...i have had my evo off the road since before christmas, since then i had a few things painted and a general tidy up.
all built up today, thought id take it out to loosen off brakes etc, taking it very very slowly, about a mile from my house, evo just cuts out compleyely and rolls to a stop.
1st thought were it wasnt getting fuel, checked that and def getting fuel so next i checked was the spark...pulled out plug 1/2 and no spark.
anyone any ideas?

Coil pack,

done a bit off research, im thinking either resistor pack or crank shaft sensor.

Could be a whole line of things wrong buddy, best off starting with summat more simple, if you know anyone with a Evo grab their coils and give it a go, free for starters and after that you can look at things like crank sensors n stuff

Doubt it's your crank sensor. No spark only on 1 and 2? I'd go with a coil pack....
Try fault code reading!!!!

1 and 2 are feed by different coil packs so unlikely they both gone down at the same time. I'd say crank sensor or imobiliser issue

sorry, i only tried one off the packs and there was no spark. i should off made that clearer, sorry

cheers buddy, ruled out imobiliser issue as when its imobilised, i think im right in saying that the fuel pump wont prime and its getting fuel im clueless, hope that makes sense

Have you pinned out the OBD and checked the fault code yet mate? Crank sensor will throw up fault code 22.

scratches head....em no ha ha. mate, im not mechanically minded in the slightest.
if you could give me a idiot guide...a vert big idiot guide on how to, ill go check tonight or tomorrow and ill send payment asap to you if its what i need

Connect (bridge) pins 1 and 4 together on the OBD under the steering wheel using a wee bit of wire, put ignition back on and count the flashes of the engine light on the dash.

12 airflow sensor system
13 intake air temp system
14 tps
21 coolant temp sensor
22 crank angle sensor
23 cam sensor
24 vechicle speed sensor
25 barometric pressure sensor
31 detonation sensor system
41 injection system
44 ign coil/power transistor system
64 alternator fr terminal system

ayc codes are different
ayc codes:4/5/6
12 power supply open or short circuit
21 fr right wheel speed sensor open or short circuit
22 fr left wheel speed sensor open or short circuit
23 rear right wheel speed sensor open or short circuit
24 rear left wheel speed sensor open or short circuit
25 wrong diam tyre
26 faulty wheel speed sensor
31 steer sensor system(st1,st2,stn)open circuit
32 steer sensor stn short circuit
33 steer sensor stn system
34 steer system st1 st2 short circuit
41 tps open or short circuit
51 longitudinal acc sensor open or short circuit
52 longitudinal acc sensor
56 lateral acc sensor open or short circuit
61 stop lamp switch system open-circuit
65 abs monitor system open or short circuit
71 proportioning valve system open or short circuit
72 directional control valve right open or short circuit
73 directional control valve left open or short circuit
81 ayc relay system open or short circuit
82 electric pump system
83 electric pump system


Hope this helps.

awesome mate, ill go do it right now mate. could you please describe what the "OBD" looks like and how will i know pins 1 and 4?
thanks again bud

It's under the dash below the steering wheel. You'll need to ly on your back with head in the footwell. You'll see the port an if you look close you'll see the pins are numbered

cheers mate, ill go out and have a look just now, if im not back in 5 mins, i have either not found it or i have got my head and body stuck in my cage

looks like a scart socket mate

will it be connected or disconnected? im guessing disconnected?:blush:

right ok, i bridget pin 1 and 4 but when i put ignition on...my abs light flashes randomly and my "ayc" lights all flash on and off but no engine light flashing, just comes on as normal then goes out after a second or two

just took the wire back out and put it back in and put ignition back on and no engine management light flashing still but the "tarmac gravel snow" lights(all 3 together) flash 4 times quite slowely the 6 times slightly faster then just keeps repeating that
arghhhh help

right ok, after alot off confusion this is what i have got back
12,13,14,22,23,24 and 32(??)
12...airflow
13...intake air temp
14...tps
22...cranks angle sensor(my guess this is problem)
23...cam sensor(this coming on cause code 22???)
24...speed sensor
32..maybe 31(detonation system sensor....i hope not)

the ABS codes its bringing up mean something mate. Long flashes are the first digit i.e 4 long flashes is 4, short flashes is the next number, i.e 4 short= code 44

That would say error code 46 you are seeing above, not sure on that one without seeing the car.

If you disconnect the battery for about 5 minutes it clears the error codes. When i had a faulty crank sensor the error code was intermittent, was a tough one to find, tell me have you changed your belts recently?
