NEWBIE HELP REQUIRED

[TA23]

Hello all,

I have just fitted an EFI 2TG engine ( with MegaSquirt II ) to a 76 Model Toyota Celica.
The engine and ECU module were working together prior to changeover.

The engine will crank but not start.
Is there a common mistake that new folks make that stops the injectors opening?

things I have checked:
all sensors seem to be working correctly on Tunerstudio
fuel at pressure in the fuel rail
spark at the sparkplugs
injectors have power, and work in "Test" mode

I have attached a log file of the engine cranking.
is there any obvious problems to the experienced eye?

thanks in advance Steve

Hello Steve,

Are the injectors getting power whilst the motor is being cranked? Have a look-see, let us know!

** should I check the voltage at the injectors while cranking the engine?

I have a fusebox supplying the injectors, via a relay (energised via the ignition ON switch) from the battery.

Yes, check the voltage at the injectors at crank. Use an indicator lamp or something as a load, too.

DOH! Found a problem.
The fuel pump is still from the original carby setup and only delivers 3psi, looks like we need another fuel pump that delivers HIGHER pressure.

Ah ha! It sounds like you're getting there now.
