Could really use some help

[fixkick]

i found your post.
the stock filter is gone
the stock banjos rusted out, as ALL do. and are NOW GONE,
and you put in other parts, non stock parts. there, sure.... (suz hoses are $$$$)
that means the pressure test port is now missing on this car
unless you put in the Tee fitting in front of the filter. pump side
like this,, pump>>>>Tee>>>>filter-in, filter,>>>filter out and to TBI body.. . then FPR then to return line.

some wise folks use Tee with Schrader valve (fuel rated) on the TEE port so standard fuel gauge tools all work. as many cars new have.


if you had bought the 20 buck kit from harbor fright(pun), it has that fitting Tee.
seen here (top arrow is TEE fitting)





ps. idle surge is a other issues. might be above and idle speeds we fix last when engine runs correctly. (power full , no misfiring)

if the ECU can not control idle , IT surges the ISC valve( super dangerous today, ask toyota the cost of the error, recalls,etc)

you need to meaure the pressure correctly
or buy a new FPR and pray,
but in the end, if the pump fails the shunt test its no good or wrong pump.
