hi..
for a hard-to-start situation on an SVX ..
when it runs right ...and nothing is really that wrong..
consider or check if the start signal is getting to the ecu.
I have seen a simple wire splice on 'that wire' pull apart..
and the only symptom was longer cranking times.
the normal way it should start is explosively even ..not even click-vroom ..
but the vroom so fast you don't hear any click from the starter in the first
place.
they should start that well.
DO FIND OUT if your 02 light is your CEL.
Also ..
say whether it's OBD-I or -II.
in either case..
an SVX engine will likely always have a few codes set..such as will occur
when the ecu does not see the right signals from the transmission ecu it
used to talk with , in the SVX car..
so unless something clever has been done to fool the ecu into happiness on
those odd inputs..
there will always be a CEL on.
just for starters you need to know if it's OBD-I or -II.
and if the 02 warning light is the CEL.
and if codes are set ...
it's nice to know what they are.
all conversions 'should' come with a full set of wiring diagrams used to
build the wiring harness, and diagrams and instructions on the custom wiring
and changes that were done to the van ..
such as how the CEL works ,
and how to get it into 'code-flashing' mode if it's OBD-I.
if you know what an OBD-II interface connector looks like..
look for it ..usually near the ecu ...........or if trying to be really
official and legal it would be near the steering column...or near the
ignition switch.
I have seen some very bogus conversion work ..
even from high end expensive conversion shops.
my saying on it is ....
"People don't really mind that it's expensive............they just want to
get what they paid for."
