Op com results help needed

dewismotorsport

Hi folks finally worked out what's wrong with my car after buying op com, fault codes I got:

Not sure what bottom one means?

I will buy a new MAP sensor tomorrow, anyone know where abouts it's located?

Thanks in advance

Daz

Those codes are not present , so in thoery shudnt be causing an issue...

What both of them? And how can you tell if there current or not?
Never used op com before sorry

dewismotorsport

Ah seen the not present part now! But the car won't start so must be to blame as nothing else has showed up, I've never replaced the Map sensor before so not a old code as I have deleted old codes off before now using a obd reader

Daz

On the screen shot it says not present at the end of the description, if the fault was there is would say current, or intermittant and sometimes even pending...

dewismotorsport

Is it worth deleting them via op com and trying again?

Daz

Yup... delete the codes, run the car till the fault ure getting occurs again and then check the codes again,,, what car are you getting the issues with?

Trouble is car doesn't run it doesn't start see other thread:

can try map sensor as they are cheap to replace

however code is inactive

put ignition on and run actuator tests like fuel pump

Will try map sensor, and I've already ran the other function tests and all was fine

Have tried a new map sensor and still no different :cry:

Have cleared codes and tried re starting and still no joy I'm seriously running out of ideas now :confused:

Chain hasn't broke as I checked and even tried the spare key and transponder, the car sparks and fuels but doesn't run :dunno:

Things changed:

spark plugs
Coil pack
Crank sensor
Throttle bodie
Map sensor
Fuel pump

Not got one at home so will bring one back from next weekend. Tbh though it drove fine on motorway then just sunddenly died so don't think that will show up anything really.

Am gonna check the timing on it as I've got to go back to basics really as I have fuel and spark so just need to confirm I'm getting them at the right time

MikeS

does it even attempt to fire up or simply turns over ?

Just turns over doesn't even attempt to fire

MikeS

should at least fire up if it has spark and fuel

In theory yes but there not so gonna check the timing as that's the only other thing needed for it to run realistically

MikeS

when u switch ignition on do you hear the fuel pump prime? - pressurises fuel lines !

when you turn her over you have taken coil pack out and actually seen the sparks ?

i am by birmingham airport so happy to have a mooch as u is in cov

Yeah the fuel pump primes and it is fueling, I've also tried another known working pump, have replaced coil pack and no different can get spark at plug ends when cranking.

And that would be great if you could take a look I live in Canley which is airport side of Coventry. I'm only back at weekends as I work away but if you pm me your mobile number we can arrange

Cheers Adam

One thing I did notice is when I crank it over the ABS and TC light flash on, then when I stop cranking they go off. Is this normal? As I can't remember. They were the first lights to come on when it cut out on the motorway
