nissan hardbody pick up immo

[makura]

HI guys

I have a nissan hardbody pick up with ecu number (nissan hitachi MECM-W895 A1 2904
23710 9s100

Now when i try to start it or when i turnthe key on the engine check light flashes like three or four time then stops,when i try to crank the engine the light flashes continues until i stop cranking.
how do i go about solving this problem,i have almost all the tools that can be used.
I have SSB,ad90,tms370 programmer,kwp2000 plus,elm327.

Is it 4 or 6 cylinder and what colour is ecu plug ?

Is it 4 or 6 cylinder and what colour is ecu plug ?
its a 4 cylinder and the ecu plug is white but the socket on the ecu itself is blue

[ecufix]

there is a 8 pin smd storage device (ic 900 or 901) just remove and start .havent worked out why but it works

[makura]

Thanks,will try it and let you know how it goes

Hi
This one does'nt have the ic900 or 901,the only 8pin chips are i501 and i907
will try removing i501,its the one closest to the micro controller.will let you know if i have any luck.

Hi
I did the above procedure and the results still negative,when the chip is off,when i put the key on the engine light comes on for a few seconds then goes off,when i start cranking the engine the light comes back and keeps flashing for as long as i am cranking the engine.
By the way when the client brought the ecu he said it was a 4 cylinder when actualy its a v6.i think the memory chip on the ecu is a 93c86.
Is there any other trick i should try or can some one kill the immo if i can read the eprom?

[ecufix]

it only works on 4 cyl . try get hold of a ssb and program key to vehicle
good luck

Hi makura i have the same exact problem...same ecu... i bought another one same results. I have been struggling for the whole week.. did you manage to solve the problem? Please kindly share your solution....

Did you even try doing a obd2 scan to see if you get immo codes???? As far as I know about nissan, it will not even start if it got an immo problem, also it will lock the ecu after 5 times starting, if you're not getting any codes could be a block catalytic converter, others could be the ones below. check also for bad fuel.

Some of the most common culprits behind a blinking engine light are as follows:

Ignition coil has failed
Fuel injector has failed
Engine computer has failed
Spark plug
Spark plug wire
Bad engine valves
