i have a 97 p reg audi a4 1.8 with a starting problem

it cranks over but wont start as there is no spark

yet when you bump start it, it starts fine runs fine

ive tried crank sensor, cam sensor, been to the local auto electrican

ive fitted new coil pack, batt, ing switch on the back of they key

ive tried everything


any help please ta.

 

ignition switch comes to mind, check all wires are connected to the starter motor

 

Put the pedal to the floor and turn the key. See if it starts that way. If so, then its likely your coolant temp sensor.

 

Hi . Thanks for the info, but I cannot see how putting the pedal to the floor can rectify a spark problem?

 

Hi, The car has been to the local auto electriacian and he surley would have picked up on any lose/disconnected wires. Any other ideas!

 

its not a spark problem if it's the coolant temp sensor to which i referred. The temp sensor, if defective, could be telling your car that it is warmer than it actually is, thus not enough fuel is delivered on crank for a "cold" start.

The pedal to the floor is a very well known and common approach to diagnosing the coolant temp sensor issue. I don't make this crap up, you know.

 

i did not say it had a colant temp fault, please read the question

 

Just because you didn’t say it or your car doesn’t know it doesn’t mean it doesn’t have a faulty coolant temp sensor, as long as the sensor is giving the motor a temp then its going to THINK its working while in reality its not, you should check it out

 

lol - got get your car read for codes... until then no one can help you.

 

yep I agree he can bump start it and all is well then its a cheap battery with no cranking amps or not enough for the car, it has to have codes stored on a no start situation
