1989 Toyota 4Runner fuel injection

Hi there, have you check fuel pressure at the rail? are there any set fault codes coming up in the ECU?

I have no tester to check for fault codes. What kind of tester will I need? What will codes tell me?

Hi there,

You will need an OBD 11 scanner with a Toyota interface, the ecu will hold set fault codes for any system that it controls, if one or more of these systems are out of parameter or not sending reference signals, you will get a dedicated fault code for that system.

Good Morning,
First of all , Thank you for all you help . Can this test be done without the engine running?

Yes, you just need the ignition on.

Hello mhpautos, !989 Toyota will still not keep running. Engine will start right up and the die. I have checked all that I will list for you. 1-fule pressure = 40PSI 2-injector resistance = 13.7 Ohms 3-Node light test = goog 4- can hear injectors clicking while enging is being cranked over 5-No codes come up on Ck. Engine light With all this being tested it still wont stay running. Any suggestions would be greatly appreciated. GOG BLESS YOU AND FAMILY IN JESUS NAME A=MEN!! M.Genzano

Hi there, OK next is to check that the spark is good and hot and clean the plugs as if the engine is not firing and the fuel system is OK as it seams it is, the plugs will be rather fuel fouled by now and that will also be a problem, let me know what the plugs look like.

Hello mhpautos, I checked spark and it is strong. Spark plugs were damp. I had installed all new plugs from the begining. I found out something while experimenting, If I put a jumped across +B - Fp ,and pump the gas peddle after engine fires as it has in the past ,I can keep the engine running for a longer period of time, but still wont stay running. HAVE A GREAT WEEK END AND GOD BLESS IN JESUS NAME A=MEN!!! M.Genzano
