Hi Beth the cars computer dosent recognise the key fob it may have fallen and lost the micro chip this would cause the problem. There is an antenna around the ignition switch that reads the chip in the key if the chip is present there could be a fault with the antenna or the ECU you will need a diagnostic computer to find out exact fault. Regards Jim...
open up the ecu these ecu used a chip set. they can be removed. there is 2 chips clipped in one for engine control timing and other one for fuel ... the chip numbers are the parts you need. also look at the can's in the ecu there is a set that over time you will need to replace. these will cause problems but dont cost alot to get replacements. the cans failing will cause none starting/ backfiring high fuel running and engine to just cut out at any speed but more prone to cut out at high rev's. i would think it would be this parts you need and not the chips as the chips only go if the battery has not been put back on right with the ignition on.
if it is just the fuel problem with the ecu, replace the chip in side the ecu from the new one you got as then you dont need to re program it then. the fuel chip and control is inside the ecu. you used to be able to get the chips for them and program the codes onto them. should be clip in type chips. if its soldered type as there are 2 types of ecu boards with same part number. you will need to un solder the chip.
Sounds like you might have an issue with your engine, it needs a compression test. Very possible it is a blown head gasket.------------------------------------------------------------------------------------ ECU Chip Tuning Tool
Automotive ECU is to convert
stored procedures chip in simple, replace the programmed chip, as long as open
the backplane of the ECU and unplug the original chip and then put the new chip
, as some older E-ROM chip only can write just one time, every time you modify
the program you must turn the program of original chip into a blank chip and
then replace the original chip. If you want to have a program modified by
yourself, you need a ecu programmer.
what you have to do is connect a noid light on the #3 injector and see if it is wirking, if not there is a broken wire or the drive for that injector in the ecu is bad, which means you need to replace the ecu
It is the sensor on the middle of air inlket manifold. but there is two sensor built to one. as I remember it was 6 or 8 wires connected. I have the rigin drawing of you like I can send you it by mail. but I recomand you not to connect this chip. I have tried severral types and the difference is very little and chance for distroying cabelsensor and get check engine light comeing all the time. If you need a chip you could try the Volo Performance chip VP 12 or you must talk with Seoulfast racing about changeing or update the ECU on your car.
